Title: Renormalon for threshold-like factorization of space-like parton correlators
Abstract: In this talk , I present our recent work on renormalon and power correction for threshold-like factorizations of space-like parton distributions (such as pPDF&&qPDF ). I show that the common Sudakov hard kernel at LP in this case has a linear IR renormalon and show how it cancels with UV renormalons for NLP operators. I will also discuss some other features of threshold expansion in this case.
