Abstract:
By considering the gab as an independent field,we have derived a covariant Polyakov string equation.The general eigenfunctions in the case of the free and fixed boundary conditions to this equation are obtained.By evaluating the trace of the fixed eigenfunctions and expanding to the leading order in 1/D expansion,we have obtained the heavy quark potential.The numerical results of ψ and γ families including energy levels,leptonic widths etc.,are in good agreement with experiment.Furthermore,we have calculated the energy levels and leptonic widths of (tt) in a wide range of t quark mass (50GeV~120GeV).
