XQCD 2018

We will present new state-of-the-art lattice QCD results on the chiral crossover temperature of QCD for moderately large baryon chemical potential. Firstly, we will present a more precise updated result for the QCD pseudo-critical temperature at zero baryon chemical potential, obtained from all possible second-order chiral susceptibilities that diverge in the chiral limit. Then we will present...

We will discuss the behaviour of the (pseudo)critical temperature of QCD as a function of the baryon chemical potential for physical quark masses. This behaviour has been extracted from 2+1 flavour lattice QCD simulations using both the imaginary chemical potential and the Taylor expansion approach; on the contrary of previous results in the literature, a good agreement between the two...

QCD equation of state at finite baryon density is studied in the framework of a Cluster Expansion Model (CEM), which is based on a fugacity expansion of the net baryon density. CEM uses the leading two Fourier coefficients from lattice simulations at imaginary $\mu_B$ as the only model input. Excellent description of the available lattice data at both $\mu_B = 0$ and at imaginary $\mu_B$ is...
