33. Fluctuations of conserved charges in strong magnetic fields from lattice QCD

Junhong Liu (Central China Normal University)

QCD phase structure in the nonzero magnetic fields has attracted intensive interest recently as the strong magnetic field is expected to be present in the early stage of peripheral heavy-ion collisions, early universe and magnetars. In this talk we show that fluctuations of and correlations among net baryon number, strangeness and electrical charge can be useful to probe the imprint of the...

58. Dynamical evolution of particle number fluctuations in hadronic transport

We study particle number fluctuations in infinite nuclear matter using hadronic transport simulations. We focus on matter initialized at a series of thermodynamically and mechanically stable points in the phase diagram, and in particular on the influence of the critical point on the equilibrated values of the fluctuations. We compare fluctuations from hadronic transport simulations against the...

Calculations of baryon number fluctuations at finite temperature and density in Ref.[1] have been extended to regime of large baryon chemical potentials with 400 MeV $\leq \mu_B\leq 650$ MeV. A peak structure is found for the dependence of the kurtosis of baryon number distributions, i.e., $R^{B}_{42}=\chi^{B}_{4}/\chi^{B}_{2}$, on the collision energy in a range of 3 GeV...

85. Measurements of Local Parton Density Fluctuations via Proton Clustering from STAR Beam Energy Scan

Quark-Gluon Plasma (QGP), a novel state describing the bulk properties of QCD matter at high energies, can be experimentally probed with relativistic nucleus-nucleus collisions. The nature of the transition between the QGP phase and the final state hadron gas phase is yet to be established. The Beam Energy Scan (BES) program at RHIC aims at searches for a possible critical point in the QCD...
