The Mass and Leptonic Decay Constant of Ds0(2317) Meson in the framework of thermal QCD sum rules

Abstract

In the present work, we assume D_{s0}(2317) meson as the c\bar{s} state and study its parameters at finite temperature using QCD sum rules. It is calculated the annihilation and scattering parts of spectral function in the lowest order of perturbation theory. Taking into account perturbative two-loop order \alpha_{s} corrections and nonperturbative corrections up to the dimension six condensates it is investigated the temperature dependences of mass and leptonic decay constant of D_{s0}(2317) meson.
