Quarkonium Decays and Production in NRQCD
Abstract
Some examples of the most recent applications of the NRQCD factorization approach to quarkonium phenomenology are presented. In the first part of the talk the NLO calculations for and decays rates are compared to the data and the results critically analyzed. In the second part, I show how information on the non-perturbative matrix elements can be extracted from the hadronic fixed-target experiments and eventually used to test their universality.
