Revisiting the charmonium spectra within the non-relativistic framework using the Matrix Numerov method

Abstract Charmonium is a composite particle composed of charm and anti-charm quark. Studying spectroscopy on charmonium one effort to understand the strong interactions. In this study, mass spectrum modeled within non-relativistic framework. As result, we can use Schrödinger equation describe system. The results obtained with framework are reasonable for because relatively large compared quark from first generation. Potential energy phenomenological potential, known as Cornell terms containing spin-spin We obtain various masses by solving using Matrix Numerov method. parameters that appear in potential adjusted comparing our calculation data spectra group (PDG). When look at PDG data, see there still many charmonia whose quantum numbers unknown. model then predict number charmonia.
