Description

I discuss factorization in SCET at next-to-leading power (NLP) for quark-induced Drell-Yan scattering at low $q_{\perp }^2$ and Deep Inelastic Scattering in the $x\to 1$ limit. Using a SCET approach with no explicit soft or collinear modes, I discuss the fact that spurious endpoint and rapidity divergences which naively spoil factorization in SCET cancel when double-counting of degrees of freedom is consistently accounted for at NLP.
