چکیده

We present results of a global tuning of general purpose Monte Carlo models to published measurements of p ! jets at HERA and ! jets at LEP and TRISTAN. The principle free parameters in the tuning are the simulation of the underlying event and the choice of photon structure. Several combinations of models are ruled out by the data.

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.

Photoproduction of jets at HERA in next-to-leading order QCD

A new next-to-leading order Monte Carlo program for the calculation of jet cross sections in photoproduction is described. The contributions from both resolved and direct components are included to O(ααs). Properties of the predictions for various inclusive jet and dijet observables are discussed and comparisons with HERA data are presented. PACS number(s): 12.38.Bx,13.60.Hb,14.70.Bh Typeset us...

Prompt Photon Plus Jet Photoproduction at HERA at Next-to-Leading Order in QCD

The cross section for photoproduction of an isolated prompt photon in association with a jet is studied in Next-to-Leading Order. The kinematics are those appropriate for the DESY ep collider HERA. The effects on the cross section of various experimental cuts including isolation cuts on the photon is examined. Comparisons with the ZEUS preliminary data using two parametrizations of the photon s...

Jet Photoproduction and the Structure of the Photon Typeset Using Revt E X 1

Various jet observables in photoproduction are studied and compared to data from HERA. The feasibility of using a dijet sample for constraining the parton distributions in the photon is then studied. For the current data the experimental and theoretical uncertainties are comparable to the variation due to changing the photon parton distribution set.
