Measurement of the exclusive photoproduction of J/PSI mesons in the reaction GAMMA P --& gt; J/PSI P in the kinematic range of W from 20 to 290 GeV,where W is the photon-proton c.m. energy. The data come from muon decays of J/P SI collected during 1996 and 1997 with an integrated luminosity of 38 pb-1 and electron decays of J/PSI collected during 1999 and 2000 with an integrated luminosity of 55 pb-1. Both data sets come from 27.5 GeV positrons colliding with 820 GeV protons for the muon data set and 920 GeV protons for the electron data set.Allcross sections are corrected for the respective branching ratios of the J/PS I decay.

description: DESY-HERA. Measurement of the di-jet cross section in photoproduction data from collisions of 27.5 GeV positrons with 820 GeV protons. The data were taken during a dedicated run in 1996 and 1997 and have an integrated luminosity of 38.6 +- 0.6 pb-1. The variable X(C=GAMMA), is defined as:& lt;p& gt; X(C=GAMMA)=(ET(JET1)*EXP(-ETARAP(JET1)+ET(JET2)*EXP(-ETARAP(JET2))/2*Y*E_e where Y is the energy fraction of the radiated photon in the proton rest frame and E_e is the positron beamenergy. X(C=GAMMA) is the fractional momentum of the photon carried by the inte racting parton. The jets are defined so that ET(JET1) & gt; ET(JET2). In all the distributions, unless otherwise stated the following kinematical ranges apply:& lt;p& gt; 134 & lt; W_GAMMA-P & lt; 277 GeV& lt;br& gt; ET(JET1) & gt; 14 GeV& lt;br& gt; ET(JET2) & gt; 11 GeV& lt;br& gt; -1 & lt; ETRAP(JET1 and JET2) & lt; 2.4.
