Description
In recent years, it has been understood that collinear factorization and QCD color coherence are violated at hadron colliders in higher orders of perturbation theory. In this talk, I will review the physical origin of these phenomena, their implications (such as super-leading logarithms and coherence-violating logarithms), and the role they play with regards to PDF factorization, which is the basis for most calculations of hadron collider observables.
