Abstract
RAMIREZ ZALDIVAR, D. A.; GUZMAN, F. and ARREBATO, D.. Charmonium: comparison between potential models. Nucleus [online]. 2018, n.63, pp. 9-11. ISSN 2075-5635.
Heavy quark has been studied in the non relativistic framework using a quark-quark potential as a sum of power of the corresponding distance. The form of potential is based on phenomenological facts. The problem was solved numerically using a program written on C++. Mass spectra and the expectation value of the radius have been estimated for different quantum-mechanical states for system. The results have been compared with other similar and recent works. The mass spectra obtained is in acceptable agreement with the experimental data for .
