Study on the applicability of Varshni potential to predict the mass-spectra of the quark-antiquark systems in a non-relativistic framework

In this work, we obtain the Schr"odinger equation solutions for the Varshni potential using the Nikiforov-Uvarov method. The energy eigenvalues are obtained in non-relativistic regime. The corresponding eigenfunction is obtained in terms of Laguerre polynomials. We applied the present results to calculate heavy-meson masses of charmonium and bottomonium .The mass spectra for charmonium and bottomonium multiplets have predicted numerically. The results are in good agreement with experimental data and the work of other researchers.
