A pedagogic model for Deeply Virtual Compton Scattering with quark-hadron duality
نویسندگان
چکیده
We show how quark-hadron duality can emerge for valence spin averaged structure functions, and for the non-forward distributions of Deeply Virtual Compton Scattering. Novel factorisations of the non-forward amplitudes are proposed. Some implications for large angle scattering and deviations from the quark counting rules are illustrated. PACS numbers: 12.39.-x, 12.40.Nn, 13.60.Hb

Exclusive photoproduction of lepton pairs at LHC
Exclusive photoproduction of dileptons, γp → `+`− p, will be measured in ultraperipheral collisions at LHC. The mechanism where the lepton pair comes from a heavy timelike photon radiated from a quark interferes with the pure QED process γγ → `+`−. As an analog of deeply virtual Compton scattering, this timelike Compton scattering is a way to study generalized parton distributions in the nucleo...
متن کاملExclusive Processes at Intermediate Energy, Quark-hadron Duality and the Transition to Perturbative Qcd
Experiments at CEBAF will scan the intermediate-energy region of the QCD dynamics for the nucleon form factors and for Compton Scattering. These experiments will definitely clarify the role of resummed perturbation theory and of quark-hadron duality (QCD sum rules) in this regime. With this perspective in mind, we review the factorization theorem of perturbative QCD for exclusive processes at i...
متن کاملLight-Cone Wavefunction Representation of Deeply Virtual Compton Scattering
We give a complete representation of virtual Compton scattering γp → γp at large initial photon virtuality Q and small momentum transfer squared t in terms of the light-cone wavefunctions of the target proton. We verify the identities between the skewed parton distributions H(x, ζ, t) and E(x, ζ, t) which appear in deeply virtual Compton scattering and the corresponding integrands of the Dirac ...
متن کاملLight Front QCD
In these lectures, I survey a number of applications of light-front methods to hadron and nuclear physics phenomenology and dynamics, including light-front statistical physics. Light-front Fock-state wavefunctions provide a frame-independent representation of hadrons in terms of their fundamental quark and gluon degrees of freedom. Nonperturbative methods for computing LFWFs in QCD are discusse...
متن کاملMeasurement of the transverse target-spin asymmetry associated with deeply virtual Compton scattering on the proton
Measurements of deeply virtual Compton scattering (DVCS) made at HERMES using 27.6 GeV e± beams and various internal polarized or unpolarized gaseous targets are discussed. Results are reported on the transverse target-spin asymmetry (TTSA) associated with DVCS, extracted from data accumulated in 2002-2004 with the e beam on a transversely polarized hydrogen target. TTSA amplitudes leading in t...
