Abstract

The cross section for the diffractive deep-inelastic scattering process ep → eXp is measured, with the leading final state proton detected in the H1 Forward Proton Spectrometer. The data sample covers the range x_ℙ < 0.1 in fractional proton longitudinal momentum loss, 0.1 < |t | < 0.7 GeV² in squared four-momentum transfer at the proton vertex and 4 < Q² < 700 GeV² in photon virtuality. The cross section is measured four-fold differentially in t, x_ℙ, Q² and β = x/x_ℙ, where x is the Bjorken scaling variable. The t and x_ℙ dependences are interpreted in terms of an effective pomeron trajectory and a sub-leading exchange. The data are compared with perturbative QCD predictions at next-toleading order based on diffractive parton distribution functions previously extracted from complementary measurements of inclusive diffractive deep-inelastic scattering. The ratio of the diffractive to the inclusive ep cross section is studied as a function of Q², β and x_ℙ.
