Abstract
Three-jet production in the reaction ep –> eXp has been studied with the ZEUS detector at HERA using an integrated luminosity of 42.74 pb(-1).The data were measured in the kinematic region 5 < Q(2) < 100 GeV2, 200 < W < 250 GeV and 23 < M-X < 40 GeV. The diffractive signal was selected by requiring a large rapidity gap in the outgoing proton direction. Jets were reconstructed in the centre-of-mass system of X using the exclusive k(T)-algorithm. A sample of three-jet events in diffraction has been identified. Differential cross sections were measured as a function of the jet pseudorapidity and jet transverse momentum with respect to the virtual photon-pomeron axis. The jets going in the pomeron direction are broader than those going in the virtual-photon direction. This is consistent with models predicting that gluons a-re predominantly produced in the pomeron direction and quarks in the virtual-photon direction. (C) 2001 Elsevier Science B.V.
