Combining TMD factorization and collinear factorization

Understand

We examine some of the complications involved when combining (matching) TMD factorization with collinear factorization to allow accurate predictions over the whole range of measured transverse momentum in a process like Drell-Yan.

• Then we propose some improved methods for combining the two types of factorization.
