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

摘要

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