7 May 1992 | Journal: | Phys.Rev. D46 (1992) 1914-1918 | Subject: | hep-lat hep-ph | Abstract: | Rigorous QCD predictions for decay rates of the P-wave states of heavy quarkonia are presented. They are based on a new factorization theorem which is valid to leading order in the heavy quark velocity and to all orders in the running coupling constant of QCD. The decay rates for all four P states into light hadronic or electromagnetic final states are expressed in terms of two phenomenological parameters, whose coefficients are perturbatively calculable. Logarithms of the binding energy encountered in previous perturbative calculations of P-wave decays are factored into a phenomenological parameter that is related to the probability for the heavy quark-antiquark pair to be in a color-octet S-wave state. Applying these predictions to charmonium, we use measured decay rates for the $chione$ and $chitwo$ to predict the decay rates of the $chizero$ and $h_c$. | Source: | arXiv, hep-lat/9205006 | Other source: | [GID 786046] pmid10015156 | Services: | Forum | Review | PDF | Favorites |
