Hadron properties at finite temperature and density with two-flavor Wilson fermions

Understand

Meson properties at finite temperature and density are studied in lattice QCD simulations with two-flavor Wilson fermions.

• For this purpose, we investigate screening masses of mesons in pseudo-scalar (PS) and vector (V) channels.
• The simulations are performed on $16^3\times 4$ lattice along the lines of constant physics at $m_{\rm PS}/m_{\rm V}|_{T=0}=0.65$ and 0.80, where $m_{\rm PS}/m_{\rm V}|_{T=0}$ is a ratio of meson masses in PS and V channels at $T=0$.
• A temperature range is $T/T_{\rm pc}=(0.8 - 4.0)$, where $T_{\rm pc}$ is the pseudo-critical temperature.
