The diffractive photoproduction of dijets has been studied using 77.6 pb -1 of data taken by the ZEUS detector at HERA. The measurements have been made in the kinematic range 0.2 < y < 0.85 and xIP < 0.035, where y is the inelasticity and xIP is the fraction of the proton momentum taken by the diffr
I compare the latest H1 and ZEUS data on diffractive dijet photoproduction with next-to-leading order QCD predictions in order to see whether a rapidity gap survival probability of less than one is supported by the data. I find evidence for this hypothesis when assuming global factorization breaking
