Complex masses of resonances and the Cornell potential

Abstract

Physical properties of the Cornell potential in the complex-mass scheme are investigated. Two exact asymptotic solutions of relativistic wave equation for the coulombic and linear components of the potential are used to derive the resonance complex-mass formula. The centered masses and total widths of the $\rho$-family resonances are calculated.Comment: 12 pages, 1 figure, 1 tabl
