We review recent theoretical developments relevant to heavy-ion experiments carried out
within the Beam Energy Scan program at the Relativistic Heavy Ion Collider. Our main focus …

Abstract This White Paper presents an overview of the current status and future perspective
of QCD research, based on the community inputs and scientific conclusions from the 2022 …

Abstract The Beam Energy Scan Theory (BEST) Collaboration was formed with the goal of
providing a theoretical framework for analyzing data from the Beam Energy Scan (BES) …

We present a comprehensive review of the theoretical and experimental progress in the
investigation of novel high-temperature quantum chromodynamics phenomena in small …

The search for the QCD critical point in heavy-ion collision experiments requires dynamical
simulations of the bulk evolution of QCD matter as well as of fluctuations. We consider two …

Hot QCD physics studies the nuclear strong force under extreme temperature and densities.
Experimentally these conditions are achieved via high-energy collisions of heavy ions at the …

This report summarizes the presentations and discussions during the Rapid Reaction Task
Force “Dynamics of critical fluctuations: Theory–phenomenology–heavy-ion collisions” …

We introduce a freeze-out procedure to convert the critical fluctuations in a droplet of quark-
gluon plasma (QGP) that has, as it expanded and cooled, passed close to a posited critical …

Causality is necessary for retarded Green's functions to remain retarded in all inertial frames
in relativity, which ensures that dissipation of fluctuations is a Lorentz invariant concept. For …

We present a general systematic formalism for describing dynamics of fluctuations in an
arbitrary relativistic hydrodynamic flow, including their feedback (known as long-time …
