Photoproduction of isolated photons at HERA in NLO QCD

نویسنده

  • Maria Krawczyk
چکیده

The NLO QCD calculation for the photoproduction of the isolated photon with a large pT at the HERA ep collider is presented. The single resolved photon contribution and the QCD corrections of order αs to the Born term are consistently included. The sizeable NNLO contributions, the box and the double resolved photon subprocesses, are taken into account in addition. The importance of the isolation cut, as well as the influence of other experimental cuts on the pT and ηγ distributions are discussed in detail. Results are compared with experimental data and with the different NLO calculations. § Invited talk at RINGBERG Workshop: New Trends in HERA Physics 2001 and at Workshop on Small x Physics 2001, Cracow, June 2001 Photoproduction of isolated photons at HERA 2

Prompt photons with associated jets in photoproduction at HERA

Prompt photons, together with an accompanying jet, have been studied in the photoproduction regime of ep scattering with the ZEUS detector at HERA. Predictions based on leading-logarithm parton-shower Monte Carlo models and next-to-leadingorder (NLO) QCD underestimate the γ+jet cross sections for transverse energies of prompt photons below 7 GeV, while the kT -factorisation QCD calculation agre...

Heavy Flavor Production at Hera

Recent results of open charm and beauty production in electron proton scattering at HERA are presented. In photoproduction, the measured cross sections for charm exceed fixed order NLO QCD calculations. Experimental evidence supports the hypothesis that a significant fraction of photoproduction events with charm can be described by resolved photon processes, where the charm quark is a constitue...

Photoproduction of Isolated Photons, Single Hadrons and Jets at Nlo

The photoproduction of large-pT charged hadrons and of prompt photons is discussed, for the inclusive case and with an associated jet, using predictions from the NLO partonic Monte Carlo program EPHOX. Comparisons to recent HERA data are also shown.

Transition from Photoproduction to Deep-inelastic Scattering in Jetproduction at Hera in Nlo Qcd

We present results from NLO QCD calculations on the production of jets in ep collisions at HERA in a continuous range of photon virtuality Q. Special attention is given to the collinear singularities from the virtual photon and the resolved virtual photon component of the cross sections. Comparisons with dijet data from H1 are shown and the infrared sensitivity of dijet cross sections is discus...

Prompt photon processes in photoproduction at HERA

We present results for the photoproduction of inclusive prompt photons and for prompt photons accompanied by jets, measured with the ZEUS detector at HERA. Cross sections as a function of pseudorapidity and transverse energy are presented for 5 < E T < 10 GeV, E jet T > 5 GeV in the centre of mass energy range 120–270 GeV. Comparisons are made with predictions from leading logarithm parton show...
