Generalized parton distributions in impact parameter space
نویسنده
چکیده
We study generalized parton distributions in the impact parameter representation, including the case of nonzero skewness ξ. Using Lorentz invariance, and expressing parton distributions in terms of impact parameter dependent wave functions, we investigate in which way they simultaneously describe longitudinal and transverse structure of a fast moving hadron. We compare this information with the one in elastic form factors, in ordinary and in kT -dependent parton distributions.

Sivers Asymmetry and Generalized Parton Distributions in Impact Parameter Space
Recently, it has been pointed out that there exists a connection between the generalized parton distribution E(x, 0, t) and the Sivers asymmetry. For transversely polarized nucleon targets, generalized parton distributions are asymmetric in impact parameter space. This impact parameter space asymmetry, together with the final state interaction of the active quark, gives rise to the Sivers asymm...
متن کاملImpact Parameter Space Interpretation for Generalized Parton Distributions
The Fourier transform of generalized parton distribution functions at ξ = 0 describes the distribution of partons in the transverse plane. The physical significance of these impact parameter dependent parton distribution functions is discussed. In particular, it is shown that they satisfy positivity constraints which justify their physical interpretation as a probability density. The generalize...
متن کاملGeneralized 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 کاملSpin densities in the transverse plane and generalized transversity distributions
We show how generalized quark distributions in the nucleon describe the density of polarized quarks in the impact parameter plane, both for longitudinal and transverse polarization of the quark and the nucleon. This density representation entails positivity bounds including chiral-odd distributions, which tighten the known bounds in the chiral-even sector. Using the quark equations of motion, w...
متن کاملStructure of the Nucleon Spin on the Light Cone
The spin structure of the nucleon is studied in a light-cone description of the nucleon where the Fock expansion is truncated to consider only valence quarks. Transverse momentum dependent parton distributions and transverse-spin densities, defined through the generalized parton distributions in the impact parameter space, are investigated as new tools to reveal the spin-spin and spin-orbit cor...
