Abstract
Differential cross sections for dijet photoproduction in association with a leading neutron using the reaction e + + p → e + + n +jet+jet+ X r have been measured with the ZEUS detector at HERA using an integrated luminosity of 6.4 pb −1 . The fraction of dijet events with a leading neutron in the final state was studied as a function of the jet kinematic variables. The cross sections were measured for jet transverse energies E T jet >6 GeV, neutron energy E n >400 GeV, and neutron production angle θ n <0.8 mrad. The data are broadly consistent with factorization of the lepton and hadron vertices and with a simple one-pion-exchange model.
