Leading proton production in deep inelastic scattering at HERA

                 ZEUS Collaboration

The semi-inclusive reaction e+p -> e+Xp was studied with the ZEUS detector 
at HERA using an integrated luminosity of 12.8 pb-1. The final state 
proton, which was detected with the ZEUS leading proton spectrometer, 
carried a large fraction of the incoming proton energy, x_L > 0.32, and 
its transverse momentum squared satisfied p_T2 < 0.5 GeV2; the exchanged 
photon virtuality, Q2, was greater than 3 GeV2 and the range of the masses 
of the photon-proton system was 45 < W < 225 GeV. The leading-proton 
production cross section and rates are presented as a function of x_L, 
p_T2, Q2 and the Bjorken scaling variable, x.
