The Mass and Leptonic Decay Constant of D_(s0)(2317) Meson inthe Framework of Thermal QCD Sum Rules

摘要

In the present work, we assume D_(s0)(2317) meson as the a state and study its parameters at finite temperature. Taking into account perturbative two-loop order as corrections to the correlation function and nonperturbative corrections up to the dimension six condensates we investigated the temperature dependences of mass and leptonic decay constant using thermal QCD sum rules method.
