Virtual Compton Scattering at Low Energies ∗
These lectures give a pedagogical introduction to real and virtual Compton scattering at low energies. We will first discuss real Compton scattering off a point particle as well as a composite system in the framework of nonrela-tivistic quantum mechanics. The concept of electromagnetic polarizabilities is introduced. We then address a description of the Compton-scattering ten-sor within quantum...
متن کاملDeeply Virtual Compton Scattering at HERMES
The HERMES experiment at DESY, Hamburg used the HERA 27.6GeV electron/positron polarised beam to study the structure of the nucleon. Deeply Virtual Compton Scattering (DVCS) provides access to Generalised Parton Distributions (GPDs) via measured azimuthal asymmetries. Data was collected from 1995 to 2007 with both longitudinally and transversely polarised gas tar-gets(H, D or heavier nuclei), w...

Virtual Compton Scattering at High EnergyZHANG CHEN In this dissertation we develop a theoretical framework in the context of per-turbative QuantumChromoDynamics (pQCD) for studying non-forward scatteringprocesses. In particular, we investigate a non-forward unequal mass virtual Comptonscattering amplitude by performing the general operator product expansion (OPE)and the for...
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 کاملDeeply 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 ...
