Factorization, Effective Field Theory, and B-> D^(*) X Decays

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 N_c limit, or a combination of the two.
