Auxiliary Field Meson Model at Finite Temperature and Density
H. Kouno, T. Sakaguchi, K. Kashiwa +4
Starting from many quark interactions, we construct a nonlinear sigma-omega model at finite temperature and density. The mesons are introduced as auxiliary fields. Effective quark-…

An asymptotic formula for models with caustics
T. Sakaguchi
We introduce an asymptotic formula for calculating quantum mechanical and quantum theoretical models with caustics, like the Nambu--Jona-Lasinio(NJL) model. This asymptotic formula…
