Generalized Parton Distributions, Deeply Virtual Compton Scattering and TMDs
Parton distributions in impact parameter space, which are obtained by Fourier transforming GPDs, exhibit a significant deviation from axial symmetry when target and/or quark are transversely polarized. In combination with the final state interactions, this transverse deformation provides a natural mechanism for naive-T odd transverse single-spin asymmetries in semi-inclusive DIS. The deformatio...
متن کاملDeeply virtual Compton scattering and generalized parton distributions
We present a comparison of a recently proposed model, which describes the Deeply Virtual Compton Scattering amplitude, to the HERA data.
متن کاملGeneralized Parton Distributions from Hadronic Observables
We propose a physically motivated parametrization for the unpolarized generalized parton distributions, H and E, valid at both zero and non-zero values of the skewness variable, ζ. At ζ = 0, H and E are determined using constraints from simultaneous fits of experimental data on both the nucleon elastic form factors and the deep inelastic structure functions. Lattice calculations of the higher m...
متن کاملDeeply-virtual Compton Scattering
We study in QCD the physics of deeply-virtual Compton scattering (DVCS)—the virtual Compton process in the large s and small t kinematic region. We show that DVCS can probe a new type of off-forward parton distributions. We derive an Altarelli-Parisi type of evolution equations for these distributions. We also derive their sum rules in terms of nucleon form-factors of the twist-two quark and gl...
متن کاملDeeply Virtual Compton Scattering
We propose to measure the Beam Spin Asymmetry (BSA) in Deeply Virtual Compton Scattering (DVCS) off 4He. The measurements will use a 6 GeV polarized electron beam, a 4He pressurized gas target, the CLAS and the BoNuS RTPC detectors. The major goal of this proposal is to perform the first fully quantitative investigation of the DVCS reaction off a nuclear target in the coherent and incoherent ch...
