Hadronic Annihilation Decay Rates of P-wave Heavy Quarkonia with Both Relativistic and QCD Radiative Corrections
Han-Wen Huang
Abstract
Hadronic annihilation decay rates of P-wave heavy quarkonia are given to next-to-leading order in both αs and v2. They include ten nonperturbative parameters, which can be rigorously defined as the matrix elements of color-singlet and color-octet operators in NRQCD. We expect these papameters will be determined from lattice calculations in future.
