Exclusive quarkonium production or decay in soft gluon factorization

Exclusive quarkonium production or decay in soft gluon factorization

Abstract In this paper, we study the application of the recently proposed soft gluon factorization (SGF) to exclusive quarkonium production or decay. We find that in the nonrelativistic QCD factorization framework there are too many nonperturbative parameters. Thanks to the factorization of kinemati...
