Abstract

We show that one-jettiness (τ1) in color-singlet plus jet production suffers from superleading logarithms starting at order αs4ln(1/τ1)6 relative to the Born level. This is one logarithm more dominant than any previously identified superleading logarithms. The extra logarithm is not associated with additional poles, and is therefore consistent with the factorization of universal parton distribution functions at scale τ1Q, where Q is the hard scale.
