219. The QCD Equation of State at $\mu_B$ > 0 from Lattice QCD

Hiroshi Ohno (University of Tsukuba)

2/3/17, 2:00 PM

In this talk I will show our recent lattice studies on the QCD equation of state (EoS) at non-vanishing baryon chemical potential. The QCD EoS has been calculated with Taylor expansions including contributions from up to sixth order in baryon, strangeness and electric charge chemical potentials in a temperature range between 135 and 330 MeV. Using 4 different sets of lattice cut-offs,...

94. Fluctuations of conserved charges from the lattice

Dr Szabolcs Borsanyi (University of Wuppertal)

2/3/17, 2:25 PM

Fluctuations of electric charge, baryon number and strangeness are well defined observables in the QCD grand canonical ensemble. They can be calculated on the lattice at zero and small chemical potential and can be measured in the RHIC or LHC experiments at chemical freeze-out. We review the recent lattice results for higher moments of these fluctuations and discuss their use in heavy...

220. The RHIC beam energy scan program, the search for the QCD critical point, and reasons to be optimistic

Paul Sorensen (Department of Energy and Brookhaven National Lab)

2/3/17, 2:50 PM

Before the search for the Quark Gluon Plasma (QGP) commenced at RHIC, it was hoped that the QGP could be discovered through the observation of non-monotonic trends in a variety of observables. These smoking-gun signals were not observed in the data taken at higher beam energies, and the discovery of the perfect liquid QGP relied on careful comparisons between models and data. No non-monotonic...
