Experimental Particle Physics Group Jets and Prompt Photons in Photoproduction at Zeus
نویسنده
چکیده
In the ZEUS experiment at HERA, photoproduction processes have been studied for photon-proton centre-of-mass energies in the range 100 < Wp < 300 GeV and jet transverse energies extending to E jet T 70 GeV. The data contribute to our understanding of QCD dynamics, and also provide new constraints on the photon's parton density.

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...

متن کاملPrompt Photons in Photoproduction at HERA
The production of prompt photons in photoproduction reactions in the ZEUS experiment is discussed. Cross sections for inclusive prompt photons and for prompt photons accompanied by jets are compared with theory, and the latter are used to determine the effective transverse momentum of the quarks in the proton.
متن کاملPrompt 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...
متن کاملPhoton Structure in Γp Interactions on Behalf of the Zeus Collaboration
Photoproduction of jets at HERA provides information on the partonic structure of the photon. We report on the latest dijet photoproduction results, for real photons and for photons at low virtualities, measured with the ZEUS detector.
