Complex Masses of Resonances in the Potential Approach

Abstract

Quarkonium resonances in the complex-mass scale are studied. Relativistic quark potential model is used to describe the quark-antiquark system. The complex-mass formula is obtained from two exact asymptotic solutions for the QCD motivated potential with the distance-dependent value of the strong coupling in QCD. The centered masses and total widths of some meson resonances are calculated. A possible origin of the ``dark matter'' and the ``Missing Mass''is discussed.
