  1. 60. Studying Hadronization by Machine Learning Techniques
    Gabor Biro (MTA Wigner FK)
    16/05/2022, 14:00

    Hadronization is a non-perturbative process, which theoretical description can not be deduced
    from first principles. Modeling hadron formation, requires several assumptions and various
    phenomenological approaches. Utilizing state-of-the-art Computer Vision and Deep Learning
    algorithms, it is eventually possible to train neural networks to learn non-linear and non-
    perturbative features of...

  2. 38. Estimating Elliptic Flow Coefficient in Heavy Ion Collisions using Deep Learning
    Gergely Barnafoldi (Wigner RCP RMI of the Hungarian Academy of Sciences)
    16/05/2022, 14:25

    Machine Learning (ML) techniques have been employed for the high energy physics (HEP) community since the early 80s to deal with a broad spectrum of problems. This work explores the prospects of using Deep Learning techniques to estimate elliptic flow (v2) in heavy-ion collisions at the RHIC and LHC energies. A novel method is developed to process the input observables from track-level...

  3. 62. Scaling properties of jets in high-energy proton-proton collisions
    Robert Vertesi (MTA Wigner RCP RMI)
    16/05/2022, 14:50

    Measurements of jet profiles in high-energy collisions are sensitive probes of
    QCD parton splitting and showering. Precise understanding of the jet struc-
    tures are essential for setting the baseline not only for nuclear modification of
    jets in heavy-ion collisions, but also for possible semi-soft cold QCD effects such
    as multi-parton interactions (MPI) that may modify jets in...

  4. 61. The role of the underlying event in the charmed-baryon enhancement in high-energy pp collisions
    Zoltan Varga (Wigner RCP)
    16/05/2022, 15:10

    The production of heavy-flavor hadrons is usually described using the factorization hypothesis, in
    which the production cross section is expressed as convolutions of three independent factors: the
    parton distribution functions (PDF) of the colliding hadrons, the production cross-sections of the
    heavy-quarks in the hard partonic process, and the fragmentation functions of the heavy-quarks...

  5. 53. Dissipative relativistic dense hadro-partonic fluids with strangeness production
    Prof. Ludwik Turko (Univeristy of Wroclaw)
    16/05/2022, 15:50

    Heavy Ion Collisions (HIC) provided the possibility of researching the phase transitions from hadronic matter to the predicted Quark-Gluon Plasma (QGP) phase based on partonic degrees of freedom. Conditions at HIC – nuclear densities much higher than nuclear density and/or temperatures above 150 MeV – suggest such a form of matter both dominant just after the Big Bang as in the cores of...

  6. 63. Nonextensive statistics and multipatricle production processes
    Prof. Maciej Rybczyński (Jan Kochanowski University)
    16/05/2022, 16:10

    The ubiquitous presence of quasi-power law functions
    in multiparticle production processes are discussed
    from the perspective of nonextensive Tsallis distributions.
    Special emphasis is placed on the conjecture that this
    reflects the presence in the produced hadronic systems
    of some intrinsic fluctuations.
    In particular we analyze a connection between energy
    and multiplicity...

  7. 78. Exploring the QGP phase in high multiplicity pp and A-A collisions using Color String Percolation Model at LHC energies
    Aditya Nath Mishra (Wigner Research Centre for Physics Budapest, Hungary)
    16/05/2022, 16:30

    We have analyzed the transverse momentum spectra of charged particles in high multiplicity pp collisions at LHC energies 5.02 and 13 TeV using the Color String Percolation Model (CSPM). For heavy ions, Pb-Pb at 2.76 and 5.02 TeV along with Xe-Xe at 5.44 TeV have been analyzed. The initial temperature is extracted both in low and high multiplicity events in pp collisions. For heavy-ion...

  8. 59. New insights into the mass generation and structure of the QCD ground state
    Vakhtang Gogokhia (HAS, RMKI, KFKI, Depart. of Theor. Phys.)
    16/05/2022, 16:50

    We present reports on progress in the solution of the mass dynamical gen-
    eration problem in particle physics at the fundamental level of the strong
    interactions. It is based on new significant insights into the true dynamical
    and gauge structures of the QCD ground state. The conclusive proof has
    been given that the structure of the QCD ground state is much more com-
    posite than it is...

  9. 34. The Polyakov and Wilson loops in Hamiltonian form
    Prof. Rob Pisarski (BNL)
    16/05/2022, 17:10

    I give a general analysis of how to represent Wilson loops in the
    Hamiltonian formulation. This requires enlarging the physical
    space of states to include the external charge on the Wilson loops. The character representation is used in an essential manner. As a byproduct, it demonstrates how to continue the Polyakov loop, which appears peculiar to imaginary time, to real time.
