Abstract

Three- and four-jet final states have been measured in photoproduction at HERA using the ZEUS detector with an integrated luminosity of 121 pb −1 . The results are presented for jets with transverse energy E T jet > 6 GeV and pseudorapidity | η jet | < 2.4 , in the kinematic region given by the virtuality of the photon Q 2 < 1 GeV 2 and the inelasticity 0.2 ⩽ y ⩽ 0.85 and in two mass regions defined as 25 ⩽ M n j < 50 GeV and M n j ⩾ 50 GeV , where M n j is the invariant mass of the n-jet system. The four-jet photoproduction cross section has been measured for the first time and represents the highest-order process studied at HERA. Both the three- and four-jet cross sections have been compared with leading-logarithmic parton-shower Monte Carlo models, with and without multi-parton interactions. The three-jet cross sections have been compared to an O ( α α s 2 ) perturbative QCD calculation.
