  1. 32. Chiral spin symmetry and the QCD phase diagram
    Prof. Leonid Glozman (University of Graz)
    16/05/2022, 09:10

    Above the chiral restoration crossover at T ~ 150 MeV the QCD effective action is approximately chiral spin symmetric. It is a symmetry of the color charge in QCD as well as of the chromoelectric interaction. This symmetry is larger than the chiral symmetry of Dirac Lagrangian. This symmetry implies that degrees of freedom are chirally symmetric quarks connected by electric strings into color...

  3. 72. Femtoscopy with Lévy sources in 5.02 TeV PbPb collisions

    Investigation of the femtoscopic correlation functions in heavy ion collisions is an important tool to access the space-time structure of the hadron production of the sQGP. The description of the measured correlation functions is often assumed to be Gaussian or exponential, but a detailed analysis reveals that the statistically correct assumption is a generalized Gaussian, the symmetric...

  4. 35. Chiral mixing in dense matter
    Prof. Chihiro Sasaki (Univeristy of Wroclaw)
    16/05/2022, 11:00

    Finite baryon density induces a direct mixing between vector
    and axial-vector states, which yields multiple bumps and peaks around the vacuum masses of the rho, omega and phi resonances in the spectral function. The modification become significantly pronounced when the mass difference between the parity partners decreases at high density. We propose that the emergent enhancement in the...

  5. 71. Backreaction of mesonic fluctuations on the axial anomaly at finite temperature
    Prof. András Patkós (Eötvös University)
    16/05/2022, 11:30

    The impact of mesonic fluctuations on the restoration of the $U_A(1)$ anomaly is investigated non-perturbatively for three flavors at finite temperature in an effective model setting. Using the functional renormalization group, the dressed, fully field dependent Kobayashi--Maskawa--'t Hooft (KMT) anomaly coupling is computed. It is found that mesonic fluctuations strengthen this signature of...

  6. 52. Finite volume effects on the QCD phase diagram
    Győző Kovács (Wigner RCP)
    16/05/2022, 11:50

    Contrary to the field theoretical calculations in the thermodynamic limit where the volume is assumed to be infinitely large, the heavy-ion collisions always carry the effects of the finite size. For a sufficiently small system, the volume is expected to affect the thermodynamical quantities and the phase diagram of the strongly interacting matter. To study these effects one can take into...

  7. 79. Nuclear matter parameters form maximal mass compact stars
    Balázs Endre Szigeti (MTA Wigner FK)
    16/05/2022, 12:10

    Recent observation data of pulsar masses led us to estimate nuclear parameters, however. we introduced the maximal-mass compact star scenario and took into account data satisfying these criteria. We tested our method, applying the parity doublet model in the mean-field approximation at the finite chemical potential at zero temperature to investigate the recent observation data of pulsar...
