Using the Feynman's path integral with topological constraints arising from the presence of one singular line, we find the homotopic probability distributio
By introducing hyperspherical coordinates and assuming the quasiseparability of the hyperradius R from the angular variables Ω in the wavefunctions, we have so
An effective Hamiltonian including current-current coupling from the global color symmetry model is -R2 2derived.Retardation effects are introduced by the facto
