Description

I present some recent progress in the calculation of quarkonium inclusive and electromagnetic decay widths in the framework of the NRQCD/pNRQCD factorization formalism. I will express, under general dynamical assumptions, the 40 NRQCD matrix elements, which describe up to order mv⁵ all the ratios of hadronic and electromagnetic inclusive decay widths for bottomonium and charmonium states below threshold, in terms of only 6 non-perturbative universal parameters. New predictions for charmonium and bottomonium decay widths, following from this drastic reduction, will be presented.
