Chemical potential response of meson masses at finite temperature
Abstract
We study the response of meson masses to the chemical potential (∂m/∂μ) at high temperature and at zero chemical potential on Nf=2 lattice with staggered fermions. Preliminary results for the meson composed of different quarks show that ∂m/∂μ|μ=0 is negative in the confinement phase and positive in the deconfinement phase.
