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

TL;DR

This paper investigates the temperature dependence of the mass and leptonic decay constant of the D_{s0}(2317) meson, modeled as a car{s} state, using thermal QCD sum rules including perturbative and nonperturbative corrections.

Contribution

It provides a novel analysis of the D_{s0}(2317) meson's properties at finite temperature within the thermal QCD sum rules framework, incorporating two-loop corrections and higher-dimensional condensates.

Findings

Mass decreases with temperature.

Leptonic decay constant decreases with temperature.

Results relevant for understanding meson behavior in hot environments.

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.
