Masses and thermodynamic properties of a quarkonium system

Hulthen plus Hellmann potentials are adopted as the quark–antiquark interaction potential for studying thermodynamic properties and mass spectra of heavy mesons. The was rendered temperature dependent by replacing screening parameter with Debye mass. We solved radial Schrödinger equation analytically using Nikiforov–Uvarov method. energy eigenvalues corresponding wave function in terms Laguerre polynomials were obtained. present results applied calculating mesons, such charmonium [Formula: see text] bottomonium text], properties, mean energy, specific heat, free entropy. Four special cases considered when these parameters set to zero, resulting potential, Yukawa Coulomb respectively. provides satisfying comparison experimental data work other researchers.
