abstract
We present results of our simulations of QCD with two light dynamical quarks on a 32^3 X 8 lattice at a current quark mass tuned to have the Goldstone pion mass of about 230 MeV. Employing the Taylor expansion method we proposed earlier, we estimate the radius of convergence of the series for the baryonic susceptibility by using terms up to eighth order. Together with our earlier results, corresponding to the same physical parameters but on coarser lattices at respectively 1.33 times and twice the lattice cut-off (a), we were able to attempt a march towards the continuum limit.

Normalized symmetric cumulants as a measure of QCD phase transition: a viscous hydrodynamic study
A viscous hydrodynamic study shows that normalized symmetric cumulants of flow harmonics can discriminate a crossover QCD equation of state from a first-order one at 62.4 GeV Au+Au collisions.
