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 theta (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. (C) 2001 Elsevier Science B.V. All rights reserved.

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 theta (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. (C) 2001 Elsevier Science B.V. All rights reserved.
