86. Fluctuations in the mixed phase of the first order phase transition and nucleus-nucleus collisions

Roman Poberezhnyuk (Bogolyubov Institute for Theoretical Physics)

We present the analytic description of particle number (conserved charge) fluctuations within the subvolume of the thermal system in the coexistence region of the first order phase transition. Different approximations are applied for the metastable states, for the region of spinodal decomposition [1] and in the special case of a homogeneous system [2]. The results are checked within...

78. Fate of critical fluctuations in an interacting hadronic medium

Jan Hammelmann

We study the evolution of critical fluctuations in an expanding system within a hadronic transport approach.
The system is initialized with particle number distributions coupled to the critical mode and the hadron gas then evolves in time with realistic hadronic interactions \cite{Hammelmann:2022yso}.
The initialization of the system with critical fluctuations is achieved by coupling the...

51. Exploring the criticality of QCD matter with effective field theory for fluctuating hydrodynamics

Noriyuki Sogabe (University of Illinois Chicago)

11/30/22, 8:10 PM

Recently, a non-equilibrium effective field theory framework has been formulated for fluctuating hydrodynamics [1]. In this talk, we present an example of applying this novel formalism to study the critical properties of QCD. In the view that non-Gaussian fluctuations of baryon density are important for the QCD critical point search, we derive evolution equations for the critical non-Gaussian...
