The one-jettiness distribution contains super-super-leading logarithms
Abstract
We show that one-jettiness ($τ_1$) in colour-singlet plus jet production suffers from super-leading logarithms starting at order $α_{\mathrm s}^4 \ln(1/τ_1)^6$ relative to the Born level. This is one logarithm more dominant than any previously identified super-leading logarithms. The extra logarithm is not associated with additional poles, and is therefore consistent with the factorization of universal parton distribution functions at scale $τ_1 Q$, where $Q$ is the hard scale.
