Duality and corrections to the van Royen-Weisskopf formula
Description
We propose that duality can be used in conjunction with QCD calculations of the cross section for e+e- → qanti q- to evaluate relativistic and radiative corrections to the leptonic widths of the psi and UPSILON states. We use this method to discuss relativistic corrections to the van Royen-Weisskopf formula for leptonic widths. We also point out that this formula is in error by an important factor 4m2sub(q)/M2sub(n). (orig.)
