Abstract
Using the Nambu--Jona-Lasinio (NJL) model we study responses of the pion and kaon masses to changes in the chemical potential, , at zero and finite chemical potential. We find that the behavior of for the pion is quite different from that for the kaon. Our results can give a clue for future studies of on the lattice.
