Comments on the perturbation of Cornell potential in a QCD potential model

Abstract

We find in the analysis that the linear part of the Cornell potential can be treated as perturbation for a set of larger values of σs in the range 0.4 ≤ σs ≤ 0.75 with a constant shift within the range of −0.4GeV ≤ c ≤ −1 GeV. Moreover with the same range of constant shift in the Potential, we expect better results with Coulombic part as perturbation for σs ≤ 0.4.
