Title: What does kinematical target mass sensitivity in DIS reveal about hadron structure?

Abstract

We study the role of purely external kinematical approximations in inclusive deep-inelastic lepton–hadron scattering within QCD factorization, and consider factorization with an exact treat- ment of the target hadron mass. We discuss how an observed phenomenological improvement ob- tained by accounting for target mass kinematics could be interpreted in terms of general properties of target structure, and argue that such an improvement implies a hierarchy of nonperturbative scales within the hadron.
