422. First experimental test of HAL QCD lattice calculations for the multi strange hyperon - nucleon interaction with ALICE

QCD at finite temperature and baryon density

Oral Presentation

A precise understanding of the Equation of State of dense objects like neutron stars is limited by the knowledge about the hyperon interaction and the precision of the models describing the latter. Traditionally, meson exchange models are used to describe the hyperon sector and are constrained by the scarce scattering and hypernuclei data, almost exclusively available for $\Lambda$ hyperons....

QCD at finite temperature and baryon density

Oral Presentation

We calculate the mean-over-variance ratio of the net-kaon fluctuations in the Hadron Resonance Gas (HRG) model for the five highest energies of the RHIC Beam Energy Scan (BES) for different particle data lists. We compare these results with the most recent experimental data from the STAR collaboration in order to extract sets of chemical freeze-out parameters for each list. We focused on...

384. Strangeness production in $\sqrt{s_{\rm{NN}}}$ = 54.4, 27 GeV Au+Au collisions and fixed-target program at STAR

QCD at finite temperature and baryon density

Oral Presentation

Strangeness (especially the multi-strangeness) production has been suggested as a sensitive probe to the early dynamics of the deconfined matter created in heavy ion collisions. The ratios of particle yields involving strange particles are often utilized to study various properties of nuclear matter, such as the strangeness chemical potential and the chemical freeze-out temperature. The yield...

652. Equation of state for hot QCD and compact stars from a mean field approach

Anton Motornenko (Frankfurt Institute for Advanced Studies)

QCD at finite temperature and baryon density

Oral Presentation

The thermodynamic properties of high temperature and high density QCD-matter are explored within the Chiral SU(3)-flavor parity-doublet Polyakov-loop quark-hadron mean-field model, CMF. The applications of the CMF model to the lattice QCD data, heavy-ions physics, and static neutron stars are presented. In the CMF-model the transition between hadron-dominated and quark-dominated regimes is...

673. Towards a reliable lower limit on the location of the critical endpoint

QCD at finite temperature and baryon density

Oral Presentation

There have been various attempts to give lower limits on the location of the QCD critical endpoint via lattice simulations. These mostly rely on expanding the pressure in a Taylor series near zero chemical potential, and use estimators for the radius of convergence, mostly the ratio estimator. If the radius of convergence can be found, it gives a lower limit on the location of a true phase...
