Description
Soft gluon factorization (SGF) is a new approach to describe heavy quarkonium production and decay. As the SGF resums a series of velocity corrections in NRQCD approach, it is expected to have a better perturbative convergence. In this talk, I will discuss the application of SGF for both exclusive quarkonium production and inclusive quarkonium production. The result shows that the SGF has a potential to explain puzzles in the quarkonium field.
