Description

We will present lattice QCD results on the chiral crossover temperature of QCD for moderately large baryon chemical potential. Firstly, we will present a precise measurement of the QCD pseudo-critical temperature at zero baryon chemical potential, obtained from several chiral susceptibilities. Then we will present results on the QCD pseudo-critical temperature at non-zero baryon chemical potential, computed using Taylor-expansions of chiral condensate and chiral susceptibilities up to 6th-order in the chemical potential. Finally, we will present all independent thermodynamic observables along the QCD crossover such as: specific heat, compressibility, speed of sound and thermal expansion coefficient, and compare these to HRG results to look for signs of a possible QCD chiral critical point.
