The semi-inclusive reaction e(+)p -> e(+) Xp was studied with the ZEUS detector at HERA with 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(T)(2) <0.5GeV(2); the exchanged photon virtuality, Q(2), was greater than 3 GeV2 and the range of the masses of the photon-proton system was 45 <W <225GeV. The leading proton production cross section and rates are presented as a function of x(L), p(T)(2), Q(2) and the Bjorken scaling variable, x.
