    A new method of accessing information on the symmetry free energy from yields of fragments produced in Fermi-energy heavy-ion collisions is proposed. Furthermore, by means of quantum fluctuation analysis techniques, correlations between extracted symmetry free-energy coefficients with temperature and density were studied. The obtained results are consistent with those of commonly used isoscaling techniques.

    Suppression of baryon diffusion and transport in a baryon rich strongly coupled quark-gluon plasma

    Romulo Rougemont (Sao Paulo U.)🇧🇷 · Jorge Noronha (Sao Paulo U. & Columbia U.)🇧🇷 · Jacquelyn Noronha-Hostler (Columbia U.)🇺🇸

    Five dimensional black hole solutions that describe the QCD crossover transition seen in -flavor lattice QCD calculations at zero and nonzero baryon densities are used to obtain predictions for the baryon susceptibility, baryon conductivity, baryon diffusion constant, and thermal conductivity of the strongly coupled quark-gluon plasma in the range of temperatures and baryon chemical potentials . Diffusive transport is predicted to be suppressed in this region of the QCD phase diagram, which is consistent with the existence of a critical end point at larger baryon densities. We also calculate the fourth-order baryon susceptibility at zero baryon chemical potential and find quantitative agreement with recent lattice results. The baryon transport coefficients computed in this paper can be readily implemented in state-of-the-art hydrodynamic codes used to investigate the dense QGP currently produced at RHIC's low energy beam scan.
