abstract

We study the temperature dependence of the $a_1$ meson-nucleon coupling constant in the framework of the soft-wall AdS/QCD model with thermal dilaton field. Profile functions for the axial-vector and fermion fields in the AdS-Schwarzschild metric are presented. It is constructed an interaction Lagrangian for the fermion-axial-vector-thermal dilaton fields system in the bulk of space-time. From this Lagrangian integral representation for the $g_{a_1NN}$ coupling constant is derived. The temperature dependence of this coupling constant is numerically analyzed.

Deuteron gravitational form factors, generalized parton distributions, and charge density in the framework of the soft-wall AdS/QCD model
hep-ph 2024-12 conditional novelty 4.0 of 10

The deuteron is modeled as a twist-6 vector field in thermal soft-wall AdS/QCD, yielding gravitational form factors, GPDs, and charge densities whose temperature dependence is governed by a modified dilaton parameter.
