Abstract
A measurement is made of the cross section for the process ep --> eXY in deep-inelastic scattering with the HZ detector at HERA. The cross s ection is presented in terms of a differential structure function F-2( D(3))(x(p), beta, Q(2)) Of the proton over the kinematic range 4.5 < Q (2) < 75GeV(2) The dependence of F-2(D(3)) On x(p) is found to vary wi th beta, demonstrating that a factorisation of F-2(D(3)) with a single diffractive nux independent of beta and Q(2) is not tenable, An inter pretation in which a leading diffractive exchange and a subleading reg geon contribute to F-2(D(3)) reproduces well the x(p) dependence of F- 2(D(3)) with values for the pomeron and subleading reggeon intercepts of alpha(p)(0) = 1.203 +/- 0.020(stat.)+/-0.013(sys.)(-0.035)(+0.030)( model) and alpha(R)(0) = 0.50 +/- 0.11(stat.)+/-0.11(sys.)(-0.10)(+0.0 9)(model), respectively. A fit is performed of the data using a QCD mo tivated model, in which parton distributions are assigned to the leadi ng and subleading exchanges. Bn this model, the majority of the moment um of the pomeron must be carried by gluons in order for the data to b e well described.
