中国格点QCD第一届年会

In this talk, I would like to discuss recent progress in studies of QCD at finite temperature and densities within the functional renormalization group (fRG) approaches, e.g., the QCD phase structure, QCD equation of state, baryon number fluctuations, spectral functions, real-time dynamics, etc. The relevant results are compared with those obtained from recent lattice simulations. The fRG is a...

In this talk I will report our recent lattice calculations on the heavy quark diffusion in the hot medium. The calculations are carried out in the quenched approximation on large, fine, isotropic lattices. The quark masses cover physical charm quark mass, physical bottom quark mass and infinite heavy quark mass.

We present results on the second-order fluctuations of and correlations among net baryon number, electric charge, and strangeness in (2+1)-flavor lattice QCD in the presence of a background magnetic field. We extended our previous simulations with pion mass $m_\pi=$220 MeV [1] to physical pion mass $m_\pi=140$ MeV. Simulations are performed on $32^3\times8$ lattices using the highly improved...

We have performed (2+1)-flavor QCD lattice simulations using the Highly Improved Staggered Quarks (HISQ) action on $N_{\sigma}=32$ and $N_{\tau}=96$ lattices. In our lattice simulations the strange quark mass is fixed to its physical quark mass $m_{s}^{\rm phy}$ and light quark mass is set to $m_{s}^{\rm phy}/10$ which corresponds to $M_{\pi} \approx $ 220 MeV at zero temperature. We have...
