Some aspects of gravity related thermodynamics and thermodynamic related gravitation is mentioned. It will be demonstrated, that heat capacity of black holes is positive if volume is introduced as a thermodynamic state variable [1]. Then it is shown, that Newtonian gravitation is emergent in a universal nonequilibrium thermodynamic framework [2]. Finally our Eรถtvรถs balance modernisation...

to generate sufficiently high elliptic flow (v2) with only few-millibarn
2->2 partonic cross sections. With the help of the covariant Molnar's
Parton Cascade (MPC) transport solver, we investigate the influence of the
particular initial conditions, interactions, and dynamics encoded in the
partonic stage of AMPT.... -

Relativistic viscous hydrodynamics calculations can describe a wide range of observables in relativistic heavy ion collisions. However, many studies suggest that the hot and dense system created is not in local thermal equilibrium, resulting in a contradiction for the applicability of hydrodynamics. In hydrodynamic calculations, a crucial step is to convert the fluid fields into observable...

New results will be shown using our CUJET3.1 framework globally Chi^2 constrained by both soft pT<2 and hard pT>20 data as well theoretical lattice QCD data. The focus is to show the sensitivity of future precision dijet acoplanarity and single jet azimuthal anisotropy observables to different assumptions about the color dof and structure of โperfectโ QCD fluids produced at RHIC and LHC. We...

High multiplicity events of small colliding systems at LHC energies show longe-range correlations and azimutal anisothropy that are similar to those seen in heavy ion collisions with comparable multiplicities. Whether this collective-like behaviour can be attributed to the presence of a deconfined state in small systems is an open question. Recent research hints that vacuum QCD effects such as...

The Large Hadron Collider (LHC) at CERN investigates the fundamental nature of the strong interaction in collisions of protons or heavy ions that are travelling at almost the speed of light. In these high-energy collisions, heavy (charm and bottom) quarks are created in the early stages of the reaction. Since they are produced in initial hard processes and their numbers are largely unchanged...

The quark-gluon plasma, which is formed in heavy-ion collisions, can be studied by investigating how parton fragmentation is modified while passing through it. Two-particle angular correlations are useful to study the interactions of partons and the flowing medium in a transverse momentum regime where, after hadronization, jets cannot be reconstructed event-by-event above the fluctuating...

In two-particle angular correlation measurements, the distribution of charged hadron pairs is evaluated as a function of pseudorapidity (โฮท) and azimuthal (โฯ) differences. In these correlations, jets manifest themselves as a near-side peak around โฮท = 0, โฯ = 0. These correlations can be used to extract transverse momentum (pT ) and centrality dependence of the shape of the near-side peak in...

Cancer is one of the most important diseases these days. It is the second most common reason of death in Hungary, as it causes 26% of all deaths. Therefore it is an important question how to treat cancer. One of the most popular treatments is radiotherapy, which uses particles to ionize atoms and these atoms destroy the DNA of cancer cells. Radiotherapy uses two types of particles, X-ray and...

Description of dense nuclear matter rely on the experimental constraints
coming from the properties of "normal" nuclear matter found in nuclei and
observational data from neutron stars which consist of ultra dense nuclear matter.In this presentation I show how the parameters of nuclear matter (effective nucleon mass, compressibility, and proton neutron asymmetry) influence the

states can be calculated in quantum field theory. We build up a
renormalization group framework for solving the corresponding equations.
We demonstrate in the exactly solvable nonrelativistic QED case, how
these ideas work. Finally we show that in the symmetric phase of the NJL
model there is an attractive potential between the... -

The equation of state provided by effective models of the strongly interacting matter should comply with the restrictions imposed by current astrophysical observations on compact stars. Using the equation of state given by the (axial-)vector meson extended linear sigma model, we determine3the mass-radius relation and study whether these restrictions are satisfied under the assumption that most...

We study the excitation function of the low-lying charmonium state: $\Psi$(3686) in hadron-nucleus collisions taking into account their in-medium propagation. The time evolution of the spectral functions of the charmonium state is studied with a BUU type transport model. We calculated the charmonium contribution to the dilepton spectrum and show that for $\Psi$(3686) production there is a good...

The MAGIC similarity between relativistic heavy ion collisions and binary neutron star mergers is presented. Analogous dense matter equations of state, eos, yield in both, the astrophysical and the laboratory-on- earth scenario nearly identical compression, heating and isentropic expansion curves. It is demonstrated that the conjectured transition from baryonic to quark(-yonic) matter is...

The s-channel dilepton production from pion-nucleon scattering can be divided into three effective steps, 1) the pion and nucleon scattering results in an excited state of the nucleon, such as N(1440), N(1520) etc. 2) the resonance further decays into a nucleon and a gamma/rho meson, 3) the gamma/rho further decays into a pair of leptons or pions. Such process is studied with spin formalism...

Standard and non-standard entropy formulas are derived as entropic divergence from the uniform distribution based on a particular class of resetting master equations. Application to hadronization and other phenomena with preferential transition rates in the evolution of probability distribution are reviewed.

Inertial Confinement Fusion is a promising option to provide massive, clean, and affordable energy for humanity in the future. The present status of research and development is hindered by hydrodynamic instabilities occurring at the intense compression of the target fuel by energetic laser beams. A recent proposal Csernai et al. (2018) combines advances in two fields: detonations in...

In this contribution we compare deep learning techniques with traditional methods on the analysis of lattice Monte Carlo data. Specifically we investigate the reconstruction of the spectral function from the Euclidean 2-point correlation function measured on the lattice. The two quantities are related by an integral transformation and the inversion of this transform is made difficult by the...

The trajectory of both charged and neutral particles is determined by the influence of external EM fields. The interaction is either direct through the Lorentz force which dominates the dynamics of charged particles or indirect through higher order EM moments. For example, particles with a magnetic dipole moment are under the influence of a Stern-Gerlach-like force and similar interaction...

QED vacuum structure is receiving today renewed experimental interest. Here we consider super critical constant macroscopic magnetic fields on magnetars and vacuum birefringence induced by laboratory magnetic fields as probes of the QED vacuum response. Several new vacuum effects have been recognized beyond Euler-Heisenberg effective action. We study radiative corrections relevant to field...
