Approximate solutions of the Schrodinger equation with Hulthen-Hellmann Potentials for a Quarkonium system

Abstract

Hulth\'en plus Hellmann potentials are adopted as the quark-antiquark interaction potential for studying the mass spectra of heavy mesons. We solved the radial Schr\"odinger equation analytically using the Nikiforov-Uvarov method. The energy eigenvalues and corresponding wave function in terms of Laguerre polynomials were obtained. The present results are applied for calculating the mass of heavy mesons such as charmonium and bottomonium . Four special cases were considered when some of the potential parameters were set to zero, resulting into Hellmann potential, Yukawa potential, Coulomb potential, and Hulth\'en potential, respectively. The present potential provides satisfying results in comparison with experimental data and the work of other researchers.
