Chemical potential response of pseudoscalar meson masses in the Nambu--Jona-Lasinio model
O. Miyamura, S. Choe
Using the Nambu--Jona-Lasinio (NJL) model we study chemical potential response of the pion and kaon masses as a function of temperature and chemical potential, i.e., dm/dμ(T, μ). F…

Sign convention of residues in QCD sum rules
Seungho Choe
We show that signs of pole residues for octet baryons are identical in the QCD sum rule approach. To do this we compare signs of meson-baryon cou…
