Description

We present an update on the study of the finite temperature QCD phase transition at zero baryon chemical potential with 3 degenerate flavors of Mobius domain wall fermions. The simulation is performed on lattice extent $N_t=12$ with lattice spacing $a=0.1361(20)$ fm, corresponding to temperature around 121(2) MeV.
We investigate a range of quark masses and two different volumes with aspect ratios $N_{s}/N_{t}=2,3$. By analying the renormalzied chiral condensate, susceptibility and binder cumulant, we found the rapid transition at $m_q^{\mathrm{\overline {MS}}}(2\, \mathrm{GeV}) \simeq 3-4 \, \mathrm{MeV}$ for T=121(2) MeV is in the broad crossover transition region. Besides that, we will discuss the residual chiral symmetry breaking effect on chiral condensate and chiral susceptibilities between $L_s=16$ and 32.
