The potential contains unknown parameters which\nhave to be determined in order to use the potential. This is done by using the\nmeasured energy states and decay widths. The decay widths are made coincide\nwith the theoretical values calculated from formulas given by perturbative QCD.\nIn order to solve for the parameters, the Schr\u00f6dinger equation for the charmonium\nparticle is written in a dimensionless form allowing a numerical solution of the\nSchr\u00f6dinger equation. The corresponding wave function and the eigenenergies are\nsolved numerically using a MATLAB program. The solved parameter values are then\nused to calculate the masses of the lowest energy states. These masses generally agree\nwith the measured values and the values calculated from other theoretical models.\nBased on this, the Cornell potential works well as a rough model for charmonium\nand can be used to explain the structure of the measured energy states.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Riitta Pitk\u00e4nen (rpitkane@jyu.fi) on 2018-08-06T11:56:18Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2018-08-06T11:56:19Z (GMT).
