High-mass dijet cross sections in photoproduction at HERA

Source :: Physics Letters B, 531 (1-2)
Abstract: Dijet differential cross sections for the reaction e(-)p --> e(+) jet + jet + X in the photoproduction regime have been measured with the ZEUS detector at HERA using an integrated luminosity of 42.7 pb(-1), The cross sections are given for photon-proton centre-of-mass energies in the range 134 < W < 277 GeV The differential cross sections as a function of the dijet mass, M-jj, and of the dijet angular variables have been measured for 47 < M-jj < 160 GeV and compared to next-to-leading-order QCD calculations. The dijet events in the region 75 < M-jj < 100 GeV have been used to derive a 95% C.L. upper limit on the cross section for Z(0) photoproduction of sigma(e+ p --> e+ Z0X) < 5.9 pb. Upper limits on the photoproduction of new heavy resonances decaying into two jets are also presented for masses in the range between 60 GeV and 155 GeV (C) 2002 Elsevier Science B.V.
