Description

The semi-inclusive reaction ep->eXp, with a final-state proton carrying a large fraction of the incoming proton energy, xL>0.32, and trasverse-momentum squared pT^2<0.5 GeV^2, was studied with the ZEUS detector at HERA for exchnged photon virtualities Q^2>3 GeV^2 and mass of the photon-proton system 45<W<225 GeV, using an integrated luminosity of 12.8pb-1. Leading-proton production cross section and its ratio to the inclusive DIS cross section are presented as a function of xL, pT^2, Q^2 and the Bjorken scaling variable.
