Deeply Virtual Compton Scattering at Hera
The interest of the DVCS process resides in the particular insight it gives to the applicability of perturbative Quantum Chromo Dynamics (QCD) in the field of diffractive interactions. In the presence of a hard scale, the DVCS scattering amplitude factorises into a hard scattering part calculable in perturbative QCD and parton distributions which contain the non-perturbative effects due to the ...
متن کاملDeeply Virtual Compton Scattering at HERA
Deeply virtual Compton scattering has recently been studied by three HERA experiments, H1, ZEUS and HERMES, covering a broad range of kinematic regimes. We present cross section measurements of the two collider experiments in the kinematic region 2<Q<100 GeV and 30<W<140 GeV, and compare them to QCDbased calculations. HERMES measurements of azimuthal asymmetries and their kinematical dependence...
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 ...
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 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...
