| Abstract |
Measurements are presented of the production in ep interactions at HERA of dijets in conjunction with a leading neutron. The energy of the neutron is required to be greater than 400 GeV and its angle with respect to the incoming proton direction less than 0.8 mrad. Differential cross-sections have been measured in the photoproduction (Q^2 < 10^-2 GeV^2) and deep inelastic (2 < Q^2 < 80 GeV^2 regimes. Monte Carlo simulations based on standard ep interaction processes or on the one-pion-exchange model and using several parameterizations for the pion structure function are compared to the measurements. Properties of the hadronic final state are further investigated by measuring, for the fraction of dijet events containing a leading neutron in the final state, the dependence on jet and kinematical variables. |
