摘要
Two new measurements of hadronic masses at high temperature are presented. One is an investigation for temporal hadronic mass at high temperature by anisotropic lattice with optimized hadronic operator. Temporal and screening masses for 0(+/-) and 1(+/-) mesons in quench approximation are presented. in addition, spatial structure of the hadronic operator is examined. The other is a study for response of hadronic masses and couplings to chemical potential at high temperature. Method and preliminary results for light-light and heavy-light 0(-) mesons are presented.
