摘要

In this work, we estimate the mass spectra and decay properties of charmonium ( \(c \bar{c}\) c c ¯ ) using a non-relativistic potential model. We employ a potential model incorporating a Coulomb like term, representing one gluon exchange at short distances, and a screening term representing quark confinement at long distances. Spin-dependent corrections are also added perturbatively. Our results are compared with available experimental data and some other theoretical models. Based on this, we have made some comments on interquark potential.
