Description
Factorization theorems for non-global observables at hadron colliders can be used to resum super-leading logarithms (SLLs). These SLLs are closely related to collinear factorization breaking and are driven by a double-logarithmic evolution equation in an effective field theory. The compatibility of this double-logarithmic evolution with single-logarithmic PDF evolution at low scales implies stringent consistency conditions on the low-energy matrix element of this effective theory. By analyzing these contributions at the three-loop order, I will show consistency with PDF factorization. The crucial element for factorization is a genuine Glauber contribution which first arises at this order.
