Chemical potential response of meson masses at finite temperature
  We study the response of meson masses to the chemical potential ($\partial{m}/\partial{\mu}$) at high temperature and at zero chemical potential on $N_f=2$ lattice with staggered fermions. Preliminary results for the meson composed of different quarks show that $\partial{m}/\partial{\mu}|_{\mu=0}$ is negative in the confinement phase and positive in the deconfinement phase.
