We propose a general approach to freezing out fluctuations in heavy-ion collisions using the principle of maximum entropy. find results naturally expressed as direct relationship between irreducible relative correlators quantifying deviations hydrodynamic well hadron gas from ideal baseline. The method also allows us determine heretofore unknown parameters crucial for freeze-out near QCD critical point terms equation state.
We investigate the effect of quantum chromodynamics (QCD) critical point on isentropic trajectories in QCD phase diagram. out that universality equation state and third law thermodynamics require specific entropy (per baryon) along coexistence (first-order transition) line to be nonmonotonic at least one side line. Specifically, a maximum must occur. show how location relative depends parameters commonly used literature. then examine followed by adiabatically expanding heavy-ion collision...
The universality of the QCD equation state near critical point is expressed by mapping pressure as a function temperature $T$ and baryon chemical potential $\mu$ in to Gibbs free energy reduced $r$ magnetic field $h$ Ising model. parameters are, general, not universal, i.e., determined details microscopic dynamics, rather than symmetries long-distance dynamics. In this paper we out that limit small quark masses, when close tricritical point, show universal dependence on mass $m_q$....
With the highly anticipated results from Beam Energy Scan II program at RHIC being recently revealed, an understanding of particle-number fluctuations and their significance as a potential signature possible QCD critical point is crucial. Early works that embarked on this endeavor sought to estimate due presence assuming they stay in equilibrium. From these came proposal focus efforts higher, non-Gaussian, moments event-by-event distributions, particular number protons. These non-Gaussian...
The viability of adiabatic quantum computation depends on the slow evolution Hamiltonian. switching theorem provides an asymptotic series for error estimates in $1/T$, based lowest non-zero derivative Hamiltonian and its eigenvalues at endpoints. Modifications endpoints practical implementations can modify this scaling behavior, suggesting opportunities reduction by altering endpoint behavior while keeping intermediate largely unchanged. Such modifications significantly reduce errors long...
We introduce a novel freeze-out procedure connecting the hydrodynamic evolution of droplet quark-gluon plasma (QGP) that has, as it expanded and cooled, passed close to posited critical point on QCD phase diagram with subsequent kinetic description in terms observable hadrons. The converts out-of-equilibrium fluctuations described by extended hydrodynamics, known Hydro+, into cumulants hadron multiplicities can be subsequently measured. sigma field whose cause correlations between observed...

The yields of hadrons and light nuclei in relativistic collisions heavy-nuclei at a center mass energy 2.6 TeV can be described remarkably well by thermal distribution an ideal gas interacting only via the decay resonances. Given particularly small binding hypertritons relative to temperature describing (about 156 MeV), one might naturally expect hypertrions dissociate medium, making agreement hypertriton with predictions highly puzzling. puzzle is compounded fact that associated large size...
