Vector meson gravitational form factors and generalized parton distributions at finite temperature within the soft-wall AdS/QCD model
Abstrak
Abstract We investigate the vector meson’s gravitational form factors (GFFs) and generalized parton distributions (GPDs) at finite temperatures within the soft-wall AdS/ QCD model. The plotted soft-wall GFFs graphs at zero temperature are close to the hard-wall results (Abidin and Carlson in Phys. Rev. D 77:095007, arXiv:0801.3839 [hep-th], 2008). The dependence on temperature of the GFFs and GPDs is studied using the thermal dilaton approach in the soft-wall model. Plots of thermal GFFs show that they decrease in temperature increase. Also, the gravitational radius of $$\rho $$ ρ meson decreases in temperature growth and becomes zero around the critical temperature $$T_c=0.2 \mathrm{\ GeV}$$ T c = 0.2 GeV . GPDs at zero skewness are plotted and analyzed at zero and finite temperature cases.
