QCD at finite temperature and baryon density

Oral Presentation

Elucidation of the quark matter properties at finite densities is one of the goals for the Beam Energy Scan (BES) programs at RHIC. For quantitative predictions and analyses of the experimental data, an equation of state at finite chemical potentials is needed as input to hydrodynamic models.

We construct the QCD equation of state at finite chemical potentials including net baryon (B),...

575. Universality driven analytic structure of QCD crossover: radius of convergence and QCD critical point

QCD at finite temperature and baryon density

Oral Presentation

Recent lattice QCD calculations show strong indications that the chiral crossover of QCD at zero baryon chemical potential (µ) is a remnant of the second order chiral phase transition. Furthermore, the non-universal parameters needed to map temperature T and µ to the universal properties of the second order chiral phase transition also have been determined by lattice QCD calculations....

765. Characterizing baryon dominated matter with HADES measurements

QCD at finite temperature and baryon density

Oral Presentation

In heavy-ion reactions at beam energies of a few GeV per nucleon on stationary targets, QCD matter is substantially compressed (2-3 times nuclear saturation density) while temperatures are expected not to exceed T = 70 MeV. Matter under such conditions is being studied with HADES at SIS18.

This contribution discusses new experimental results on the mechanisms of strangeness production, the...

556. Skewness and kurtosis of net-strangeness, net-baryon number and net-electric charge distributions at non-zero $\mu_B$.

QCD at finite temperature and baryon density

Oral Presentation

Using recent results on higher order cumulants of conserved charge fluctuations from lattice QCD, we construct mean, variance, skewness and kurtosis of net-strangeness, net-baryon number and net-electric charge distributions at next-to-leading order in $\mu_B$. For the strangeness neutral case ($\mu_S=0$) at fixed ratio of electric charge to baryon number density ($\frac{n_Q}{n_B}=0.4$), which...

304. Probing thermal nature of matter formed at RHIC via fluctuations

QCD at finite temperature and baryon density

Oral Presentation

Evidence for thermalization of the QCD matter created in high-energy nuclear collisions has dominantly come from the agreement of the measured yield of produced hadrons with those from statistical thermal models. Ideally for a thermalized system, in addition to mean, the higher orders of the moments of the multiplicity distribution of produced particles should also show agreement with thermal...
