Research Abstract

We have formulated microscopic formulae for the additional coefficients in Israel-Stewart relativistic causal hydrodynamics. In order to discuss the relaxation-dissipation phenomena based on a lattice field theory, we propose a stochastic quantization method of a lattice field theory with Niemi-Semenof-Umezawa type complex time contour. The importance of the s-quark in the QCD matter is also investigated through the analyses of κ meson and K-π scattering length based on a lattice QCD.
