DETERMINATION OF THE MASS SPECTRUM OF MESONS, TAKING INTO ACCOUNT THE NONLOCALITY OF INTERACTION
Abstract
Choosing a propogater as the entire analytical function same Gausse in momentum space, determined modification of potential of quarks interaction, which depends of the radius confinement. Also determined the dependence of the constituent mass of the characteristic dimension of confinement. By the decrease radius of confinement the constituent mass of consist particle is increase. So the nonperturbative interaction contribution is decrease in the mass spectrum of bound state.
