Diffractive dijet production at HERA

DESY-HERA. Measurement of diffractive dijet production differential cross sections in photoproduction and DIS events in which the hadronic final state containing the two jets is well seperated in rapidity from a leading baryonic system. This baryonic system is coded here as a proton and is defined as having a massless than 1.6 GeV. Analyses are performed of both resolved and direct photoprod uction and of DIS with photon virtualities in the Q**2 range 7.5 to 80 GeV.. In the following tables the first systematic (DSYS) error is the uncorrelated error and the second is the correlated error. The definitions of the variable X(NAME=GAMMA) and Z(NAME=POMERON) are given in the paper.
