چکیده
Two results in ep physics using HERA data are discussed: a measurement of the effective transverse parton momentum in the proton by studying the production of prompt-photons in photoproduction events in the ZEUS collaboration and differential cross sections for Deeply Virtual Compton Scattering obtained by both the H1 and ZEUS collaborations.

A recent analysis of prompt-photon events in ZEUS has led to a new determination of the effective transverse parton momentum in the proton. The observation of deeply virtual Comp-ton scattering by ZEUS and H1, including a first measurement of the DVCS cross section at HERA by H1, is also reported.
متن کاملDeeply Virtual Compton Scattering and Prompt Photon Production at Hera
Recent results on the Deeply Virtual Compton Scattering (DVCS) and prompt photon productions from H1 and ZEUS experiments on the ep collider HERA are presented. A new DVCS cross section measurements of the H1 Collaboration, for photon virtualities Q > 4 GeV and photon-proton c.m.s. energy 30 < W < 140 GeV, are discussed and compared to NLO QCD calculations encoding Generalized Parton Distributi...
متن کاملDeeply Virtual Compton Scattering at Hera Ii (h1 Results)
New results on the Deeply Virtual Compton Scattering process γ * p → γp (DVCS) from H1 experiment at the ep collider HERA are presented, using data collected during the year 2004 and corresponding to an integrated luminosity of 39.7 pb −1. The DVCS cross section is measured as a function of the photon virtuality, Q 2 , the γ * p c.m.s. energy W and differentially in the momentum transfer square...
متن کاملMeasurement of Deeply Virtual Compton Scattering at HERA
In this thesis the results of the first measurement of Deeply Virtual Compton Scattering in electron–proton collisions at HERA are presented. The analysed data were taken with the H1 detector during the 1997 data taking period corresponding to an integrated luminosity of 8 pb−1. The differential cross sections dσ dQ2 and dσ dW of the reaction ep → eγp have been measured in the kinematic domain ...
