Abstract :

We investigate the dependence of the ρ meson-nucleon coupling constant on the temperature of the medium using the soft-wall model of AdS/QCD. The finite temperature profile functions for the vector and fermion fields are applied to the model having a thermal dilaton field. The interaction Lagrangian in the bulk between these fields is written as in the zero temperature case and includes minimal- and magnetictype interactions. The temperature dependence of the gρNNðTÞ coupling constant and its terms are plotted. We observe that the coupling constant and its separate terms become zero at the medium temperature near the Hawking temperature of the phase transition.
