Abstract
Diffractive photoproduction of D*(+/-)(2010) mesons was measured with the ZEUS detector at the ep collider HERA, using an integrated luminosity of 78.6 pb(-1). The D* mesons were reconstructed in the kinematic range: transverse momentum p(T)(D*) > 1.9 GeV and pseudorapidity |eta( D*)| < 1.6, using the decay D*(+) -> D-0 pi(+)(s) followed by D-0 -> K- pi(+)(+c.c.). Diffractive events were identi. ed by a large gap in pseudorapidity between the produced hadronic state and the outgoing proton. Cross sections are reported for photon-proton centre-of-mass energies in the range 130 < W < 300 GeV and for photon virtualities Q(2) < 1 GeV2, in two ranges of the Pomeron fractional momentum x(IP) < 0.035 and x(IP) < 0.01. The relative contribution of di. ractive events to the inclusive D*(+/-) (2010) photoproduction cross section is about 6%. The data are in agreement with perturbative QCD calculations based on various parameterisations of di. ractive parton distribution functions. The results are consistent with di. ractive QCD factorisation.
