Thermal QCD sum rules study of vector charmonium and bottomonium states
We calculate the masses and leptonic decay constants of the heavy vector quarkonia, J/psi and gamma mesons at finite temperature. In particular, considering the thermal spectral density as well as additional operators ...
B-c Meson at Finite Temperature
In the present work, we investigate properties of B-c meson in the basis of thermal QCD sum rules. The annihilation and scattering parts of spectral density are calculated in the lowest order of perturbation theory. Taking ...
