84. Evolving non-Gaussian fluctuations in dynamical relativistic fluid

First-principle quantitative description of fluctuation dynamics is essential for interpreting the upcoming results of the phase II of the Beam Energy Scan experiment aimed at discovering the QCD critical point. Such a formalism, based on relativistic hydrodynamics, has been developed for Gaussian fluctuations previously. Also, in our previous work, the evolution equations for non-Gaussian...

10. Cumulants from global baryon number conservation with short-range correlations

The quantum chromodynamics (QCD) phase diagram is not yet well explored. In particular, there is a significant, theoretical and experimental, effort to search for the predicted first-order phase transition and the corresponding critical endpoint between the hadronic matter and quark-gluon plasma. The fluctuations of, e.g., net-baryon number, electric charge, or strangeness are known to be...

83. Dynamics of the conserved charge fluctuations in an expanding medium

A non-monotonic net-proton kurtosis as a function of the collision
energy for very central collisions has been suggested and may be
confirmed by recent BES-II program results advocating the existence of
the QCD critical point. Fluctuations at the origin of this peculiar
behavior are produced in the highly dynamic environment of
ultra-relativistic collisions. Especially, the violent...
