Pion electromagnetic form factor at finite density
Seung-il Nam, Hyun-Chul Kim
In this talk, we introduce an effective chiral action, derived from the instanton QCD vacuum configuration, in order to study the modification of mesonic properties in medium. We p…

Magnetic susceptibility of QCD vacuum at finite density from the nonlocal chiral quark model
Seung-il Nam, Hyun-Chul Kim
We present in this talk a recent investigation on the magnetic susceptibility (chi) of the QCD vacuum at finite density, utilizing the nonlocal chiral quark model from the instanto…

Kaon semileptonic decay (K_{l3}) form factor in the nonlocal chiral quark model
Seung-il Nam, Hyun-Chul Kim
We investigate the kaon semileptonic decay (K_{l3}) form factors within the framework of the nonlocal chiral quark model from the instanton vacuum, taking into account the effects…
