Measurement of di-jet cross-sections in photoproduction and photon structure
The production of hard di-jet events in photoproduction at HERA is dominated by resolved photon processes in which a parton in the photon with momentum fraction x(y) is scattered from a parton in the proton. These processes are sensitive to the quark and gluon content of the photon. The differential...

description | The production of hard di-jet events in photoproduction at HERA is dominated by resolved photon processes in which a parton in the photon with momentum fraction x(y) is scattered from a parton in the proton. These processes are sensitive to the quark and gluon content of the photon. The differential di-jet cross-section dσ/dlog(x(y)) is presented here, measured in tagged photoproduction at HERA using data taken with the H1 detector, corresponding to an integrated luminosity of 7.2 pb-1. Using a restricted data sample at high transverse jet energy, E(T,jet) > 6 GeV, the effective patton density f(y,eff(x(y)) = [q(x(y)) + qβ(x(y)) + 9/4 g(x(y))] in the photon in leading order QCD is measured down to x(y) = 0.05 from which the gluon density in the photon is derived.
