Oral Presentation QCD at Non-zero Density

Speaker

Description

I will present recent results on the lattice QCD equation of state from the direct
reweighting approach advocated recently in 2004.10800 and 2108.09213. I will present direct results up to a baryochemical potential-to-temperature ratio of $\mu_B/T=3$. I will concentrate on the plasma phase at non-zero baryochemical potential and compare the results with those obtained from different extrapolation procedures: the Taylor expansion around zero chemical potential and some of its resummations. Our results are based on simulations 2-stout improved staggered lattices with 8 time-slices and phyical quark masses.
