NRQCD: Fundamentals and Applications to Quarkonium Decay and Production

Abstract

I discuss NRQCD and, in particular, the NRQCD factorization formalism for quarkonium production and decay. I also summarize the current status of the comparison between the predictions of NRQCD factorization and experimental measurements.
