1 Fractal Structures and Tsallis Statistics in HEP

This talk provides an in-depth analysis of the emergence of Tsallis Statistics through fractal structures in high-energy collisions in the context of high-energy physics and hadron physics. The self-similarity in the parton structure resulting from the scale properties of the Callan-Symanzik Equation is examined, demonstrating the recursive relations that allow for the emergence of Tsallis distributions. The implications of these results, including the relation between the Tsallis parameter q and the number of colours and flavours, are discussed in detail.

Moreover, both theoretical and experimental studies supporting the emergence of Tsallis
distributions in high-energy collisions, including studies on heavy-ion collisions and proton-proton collisions, are presented. The talk also explores the potential applications of non-extensive statistical mechanics in addressing longstanding problems in traditional statistical mechanics, such as non-equilibrium phenomena, anomalous diffusion, and non-Gaussian fluctuations.

Furthermore, the derivation of the Plastino-Plastino Equation from the Boltzmann Equation for systems with non-local correlations using q-calculus is presented. The solutions of this equation are compared to those of the Fokker-Planck Equation, and possible connections between q-calculus with fractal and fractional derivatives are explored. The q-calculus derivative is shown to be a continuous approximation of the Parvate-Gangal fractal derivative, and the Caputo’s fractional derivative can be obtained from the q-calculus derivative as a non-local continuous approximation of the fractal derivative.

Finally, the talk discusses the potential extension of the same theoretical approach for the study of hadron structure, in view of the z-scaling connections with the Tsallis distributions and with thermofractal structure. This comprehensive analysis provides valuable insights into the intricate relationship between fractal structures, Tsallis Statistics, and non-local correlations in high-energy collisions, highlighting their significance for the field of high-energy physics and hadron physics.

3 Sensitivity of finite volume effects to the vacuum contribution

Finite-size effects are usually taken into account in effective field theoretical models via constraints of the momentum space. This could be either discretization due to the finite spatial extent with modes determined by the boundary condition or a simple low momentum cutoff. We implemented both scenarios by applying different boundary conditions and we studied, how the treatment of the vacuum contribution affects the finite volume effects on the phase diagram and the thermodynamic quantities. A strong dependence was found on the momentum space modification and the vacuum term, which explains certain differences between previous results and highlights the importance of the scheme used in the calculations.

4 The critical endpoint at large Nc

The phase diagram of QCD is investigated by varying number of colors N_c within a Polyakov loop quark-meson chiral model. In particular, our attention is focused on the critical point(s); the critical point present for N_c =3 moves toward the μq-axis and disappears as soon as the number of color is increased. Yet, a distinct critical point emerges along the temperature axis for N_c =53 and moves toward finite density when increasing N_c further. Thus, the phase diagram at large N_c looks specular with respect to the N_c=3 results, with the first-order transition in the upper-left and crossover in the lower-right regions of the (μq,T)-plane. The pressure is also evaluated in dependence of N_c, showing a scaling with N_c^0 in the confined and chirally broken phase and with N_c^2 in the deconfined one. Moreover, the presence of a chirally symmetric but confined “quarkyonic phase” at large density and moderate temperature with a pressure proportional to N_c is confirmed.

7 Connecting electromagnetic vacuum structure with some QCD phenomena

We survey advances in EM vacuum structure building bridges between QED and QCD: High-precision vacuum birefringence experimental environments allow the probing of QED and are also sensitive to virtual axions, particles invented to rescue parity symmetry in strong interactions/QCD. Currently we explore the possible effects of short-lived or confined axions, which otherwise escape experiments depending on real, free streaming axions. Turning to strong EM field environments relevant to magnetars and heavy-ion collisions, description of the QED vacuum response requires higher-order reducible loop contributions. A nonperturbative framework for evaluating such contributions also allows the exploration of large coupling strength α, possibly leading to an improved understanding of everlasting vacuum structure in strong field QED and the
Savvidy model in QCD.

10 Highlights from the NA61/SHINE physics program

The research program of the NA61/SHINE Collaboration covers a wide range of hadronic physics in the CERN SPS energy range (beam momentum 13A - 158A GeV/c), encompassing measurements of hadron-hadron, hadron-nucleus, and nucleus-nucleus collisions. Data are analyzed better to understand the properties of hot and dense nuclear matter. This talk will present the energy dependence of quantities inspired by the Statistical Model of Early Stage and recent results of particle production properties
in p+p and centrality selected Be+Be, Ar+Sc at the SPS energies. Moreover, the current achievements and plans related to measuring open charm production will be presented.

11 Is there a limit to the strength of acceleration?

We discuss the concept of an upper limit to the electromagnetic force and its effect on charged particle dynamics. We explore two examples: the Born-Infeld (BI) theory of electromagnetism providing a limiting field – and the limiting acceleration inherent to the
Eliezer-Ford-O’Connell (EFO) formulation of the radiation reaction force. We also explore the Euler-Heisenberg-Schwinger effective action of QED. The BI limiting field strength leads to a finite charged particle energy density as well as a modification of particle dynamics in strong fields: We show the effects of the BI limiting field in relativistic heavy ion collisions. We then describe how limiting acceleration emerges from the EFO radiation reaction force and evaluate charged particle dynamics. Finally, we explore similarities between the BI and EFO formalism and search for possible connections between the two.

13 A First Look at Magnetism in the Cosmic e+e- Plasma Epoch

We extrapolate today's magnetic properties of the Universe back to the electron-positron (e+e-) era to describe novel phenomena and self-magnetization. The cosmic e+e- plasma is the most recent era which could seed the residual large-scale extragalactic magnetic fields we see in the Universe today. This plasma epoch existed between temperatures 2 MeV > T > 0.02 MeV. We show that Big Bang Nucleosynthesis (BBN) fusion occurred amidst this dense e+e- plasma. This sets the stage for the recombination period which generates the cosmic microwave background (CMB). This epoch is unique as it is the last time antimatter existed in large quantities. Using the mean field approach, we explore statistical properties of e+e- plasma, search for conditions where ferromagnetism is favorable, and propose a mechanism for the assembly of magnetic domains via matter inhomogeneities. We suggest similar matter-antimatter plasmas may still exist in the cores of unusual stars.

Speaker: Andrew Steinmetz

14 Damped dynamic electron-positron plasma in the BBN epoch

The big-bang nucleo-synthesis (BBN) occurs in a relatively dense electron-positron e-ē plasma environment, kept in thermal equilibrium by a very dense photon γ background. We describe and evaluate the static and dynamic electromagnetic properties of this unique physical environment. The collisional thermal damping/relaxation rate in the plasma is found by calculating the net electron-positron scattering rate. The damping rate is much larger than the screening mass, indicating that the mean distance between collisions is much smaller than the Debye length. We further explore how the less dense protons and already formed other light nuclear “impurities” disturb this medium. We evaluate the inter-nuclear electromagnetic potentials arising from the e-ē-γ phase space fluctuations, subject to scattering damping and allowing for the dynamical motion of the EM-field surrounding this heavy nuclear ‘dust’: Interestingly, the EM potential of the dispersed nuclear dust in the e-ē plasma matches in its theoretical properties dusty plasma theory. In BBN temperature range for the subsonic movement of ions, we find that a wake charge forms in the rear leading to the total screening of the electric potential beyond a distance of around ∼ 10^3 fm.

15 High intensity laser-particle interactions in Flying Focus regime

In this talk the “Flying Focus” (FF) regime will be introduced as a novel method of spatiotemporal laser pulse shaping [1,2]. In the FF regime, the intensity peak formed by the moving focal point can travel at any velocity, independent of the laser group velocity, over distances much longer than a Rayleigh range. This enables co-propagation of an ultra-relativistic particle beam with the laser focus, so that the electrons stay in the region of peak field intensity for prolonged interaction times. Recently (2018), focus propagation for tens of picoseconds was demonstrated experimentally [2], stimulating theoretical study of this phenomenon. We will introduce generation methods and analytical description of FF pulses with arbitrary focus velocity [3] and discuss experimental configurations in which the long laser-particle interaction time is beneficial in high-intensity field applications. Using FF pulses, we demonstrated enhancement of radiative properties in nonlinear Thomson scattering [4], amplification of radiation reaction effects [5], and guiding of the particle beams without spreading over macroscopic distances [6].

18 Application of deep learning in estimating the elliptic flow coefficient in heavy-ion collisions at the RHIC and LHC

Abstract: In recent years, deep learning has found many applications in the field of
high energy heavy-ion collisions. Deep learning technique provides a data-driven statistics based model which can help map the input and output observables. In such cases
the mapping function is difficult to formulate or is usually unknown. In this work, we
explore the prospects of using deep learning methods such as a feed-forward deep neural
network (DNN) to estimate the elliptic flow (v2) in heavy-ion collisions at the RHIC and
LHC energies. A novel method is developed to process the input observables directly
from the particle kinematic information. The proposed DNN model is trained with Pb–
Pb collisions at √
sNN = 5.02 TeV minimum bias events simulated with AMPT model.
We proceed to show that the DNN learns and preserves the centrality, energy, transverse
momentum dependence of v2 very well. We extend this work further to estimate v2 for
light-flavour hadrons such as pions, kaons, and protons. The baryon-meson v2, and the
number of constituent quark scaling are preserved by the DNN model. Error estimation
was subjected to an event simulation with additional random noise, and the proposed
DNN model is found to keep the robustness and prediction accuracy intact up to a reasonable extent. Results are compared to experimental data wherever possible.

19 Entropic complexity in quark-gluon and other plasmas

Plasmas typically involve strong nonlocal space and/or time correlations between their constitutive elements. As a natural consequence, the thermodynamically appropriate entropy typically is nonadditive, in contrast with those systems where basically local correlations dominate and are therefore satisfactorily described by the Boltzmann-Gibbs (BG) statistical mechanics, grounded on the celebrated additive BG entropy. The biunivocal connections between nonadditive entropies -- and their associated optimizing distributions --, nonlinear Fokker-Planck equations -- and their associated stationary-state distributions, which coincide with the just mentioned optimizing ones --, and the validity of the H-theorem in all cases, will be briefly reviewed. Focus will be made on the entropies S_q (appropriate for various high-energy-collision issues), S_delta (appropriate for various black-hole and cosmological issues), and S_{q,delta}, which unifies both.

20 Instabilities in chiral plasmas

Chiral plasmas exist in various environments, noticeably, the quark gluon plasma in heavy ion collisions and the electroweak plasma in early Universe and in supernovae. We discuss the possible new instabilities, which we call the chiral magnetovortical instability and chiral shear instability, that may emerge in chiral plasmas induced by the chiral vortical effect and chiral magnetic effect. The possible implications to heavy ion collisions and to supernova physics will also be discussed.

21 From Landau-Zener transitions to Hawking radiation

Landau–Zener-transitions are an essential tool in atom optics, and in particular, in accelerated optical lattices. It is amazing that despite its simplicity, the derivation of the well-known Landau-Zener-formula for the transition probability amplitude is rather involved, independent of the approach pursued. An integration in the complex plane, the asymptotic expansion of the parabolic cylinder function, or the introduction of a superadiabatic basis represent only a few of the many sophisticated techniques that eventually lead to the elementary result.
In the present talk, we employ the Markov approximation and the well-known Fresnel-integral to derive in ‘’one-line’’ the familiar expression for the Landau-Zener-formula. Moreover, we provide numerical as well as analytical justifications for our approach, and identify three characteristic motions of the probability amplitude in the complex plane.
In addition, we make the connection to Hawking radiation and report on a recent experiment [2], verifying key features of this unusual type of radiation. Our experiment is based on an analogy between quantum mechanics and surface gravity water waves.

22 Altered Probability States

The outcomes of any given measurement of any scientific observables can be considered random variables. The crucial point is to find and apply statistical methods that enable a reasonable inference of measured observables and scientific models used to describe phenomena of interest. The statistical inference, however, is contingent on the notion of probability and how this notion is applied to the description and characterization of experimental results.

Altered Probability States then appear, based on different interpretations of the notion of
probability: frequentist interpretation based on the set theory and subjective ones called also Bayesian interpretations based on extensions of logic. Frequentist interpretation, based on well-mathematically established Kolmogorov's probability treatment, is intuitively well established - similarly to the phase transition concept, although it can appear - according to its definition - only in the thermodynamic limit. Experimental tests of theoretical predictions are always incomplete, and the measurements are limited in their accuracy. Statistical inference is the process of inferring the truth of our theories of nature based on incomplete information.

The problem of estimating and measuring this incomplete information leads to the notions of entropy and its different definition, being also a separate problem by itself.
The lecture will be devoted to comparing both approaches, frequentist, and Bayesian ones, their inference methods, and ranges of applicability. Real-life examples, from physics and astrophysics, with their pros and cons will be presented.

27 Dynamical properties of nanorods embedded in fusion fuel with plasma simulation approach

Recently laser induced fusion with simultaneous volume ignition, a spin-off from relativistic heavy ion collisions was proposed [1]. This requires two sided irradiation configuration, experiments with similar setups were proved to be successful [3]. In our case, implanted nano antennas regulated and amplified the light absorption in the fusion target [2]. We studied recently the resilience of the nanoantennas in vacuum and also in UDMA-TEGDMA medium [4, 5]. These studies concluded that the lifetime of the plasmonic effect is longer in medium, however, less energy was observed in the UDMA-TEGDMA copolymer, due to the smaller resonant size of gold nanoantenna than in case of Vacuum. Here we show how the plasmonic effect behaves in an environment fully capable of ionization, surrounded by Hydrogen atoms close to liquid densities. We performed numerical simulations treating the electrons of gold in the conduction band as strongly coupled plasma. The results show that the protons close to the nanorod’s surface follow the collectively moving electrons rather than the incoming electric field of the light. The results also show that this electron screening effect is also dependent on the laser intensity.

30 The QCD phase diagram and Complex Langevin simulations

Lattice simulations of non-zero density QCD introduce the so-called sign problem, which invalidates importance sampling methods. We use the Complex Langevin equation (CLE) to circumvent the sign problem. Recent results regarding the phase diagram and thermodynamics of QCD using Complex Langevin simulations will be reviewed. We show recent theoretical results about the understanding and monitoring of failures and successes of the method, and present also comparisons of reweighting and CLE simulations with a regularization term called dynamical stabilization.
