Factorization, Effective Field Theory, and B-> D(*) X Decays
Iain W. Stewart
Abstract
In this proceedings I review the soft-collinear effective theory (SCET), an effective theory for energetic particles. I also discuss factorization in exclusive and inclusive B-> D(*)X decays, and tests which can help distinguish whether factorization is a result of a large energy limit, the large Nc limit, or a combination of the two.
