Description
In this paper we study the properties of particles in hot and dense
nuclear matter within the framework of the SU(3) Nambu - Jona - Lasinio
model. To calculate the mass and width of diquars (scalar, pseudo
scalar, vector, axial vector) as functions of temperature, the
Bethe-Salpeter equation is presented as a system of two equations. To
solve a self-consistent system of the nonlinear integral equations, a
FORTRAN code is written. The behavior of the diquark mass at finite
temperature was investigated. The obtained results are used to describe
baryons as quark-diquark pairs.
