Abstract: I will discuss the fact that for a generic class of observables in hadronic collisions, well above the weak scale, the standard parton model picture is violated due to non-factorizable electro-weak corrections at leading order in the power expansion. The mechanism for factorization violation we point out here is distinct from the canonical QCD factorization violation mechanism as it arises from the measurement of electro-weak charges in the final state. The resummation of logs can no longer be accomplished solely by following standard DGLAP and rapidity evolution equations.
