Description
We report on the investigation of the thermodynamics of 2+1 flavor QCD along the lines of constant physics (LCP) tuned on and near the physical point with Möbius domain wall fermions. The study is aiming to explore the temperature range covering (pseudo-) criticality for two lattice spacings with $N_t=12$ and $16$. In our simulations the lattice spacing covers 1.4 $> a >$ 0.6 fm, where the residual chiral symmetry breaking changes two-orders of magnitude: $3 m_{ud}^{phys} > m_{res} > 0.03 m_{ud}^{phys}$ compared with the physical average $ud$ quark mass. We discuss how one can control the effect of $m_{res}$. It is crucial for the chiral condensate, which is used for the demonstration.
