On “dual” parametrizations of generalized parton distributions

چکیده
We propose a parametrization for the generalized parton distributions (GPDs) which is based on representation of parton distributions as an infinite series of tchannel exchanges. The entire generalized parton distribution is given as an infinite sum over contributions of generalized light-cone distribution amplitudes in the tchannel. We also discuss the relations of the lowest Mellin moments of GPDs to basic mechanical characteristics of the nucleon as a compound system.

Probing quark-distribution amplitudes through generalized parton distributions at large momentum transfer.
In the large momentum transfer limit, generalized parton distributions can be calculated through a QCD factorization theorem which involves perturbatively calculable hard kernels and light-cone parton distribution amplitudes of hadrons. We illustrate this through the H(q)(x,xi,t) distribution for the pion and the proton, presenting the hard kernels at leading order. As a result, experimental da...
متن کاملGeneralized parton distributions: Status and perspectives
We summarize recent developments in understanding the concept of generalized parton distributions (GPDs), its relation to nucleon structure, and its application to high–Q2 electroproduction processes. Following a brief review of QCD factorization and transverse nucleon structure, we discuss (a) new theoretical methods for the analysis of deeply–virtual Compton scattering (t–channel–based GPD pa...
متن کاملPresent Status of Polarized Parton Distributions
A review of the present knowledge on polarized parton distributions is given. The effects of perturbative evolution on these distributions are discussed qualitatively and a comparison of various recent parametrizations is made.

متن کاملDynamical Parton Distributions for α S Determinations
Precise determinations of the strong coupling constant in hadronic collisions demand sets of parton densities spanning a sufficiently wide range of values for the QCD scale parameter Λ. For such applications, we supplement the recent GRV parametrization by five sets of dynamically generated parton distributions for Λ-values corresponding to α S (M 2 Z) between 0.104 and 0.122. Present DIS data,...

We propose a generic ansatz for the extension of parton distributions of the real photon to those of the virtual photon. Alternatives and approximations are studied that allow closed-form parametrizations. a Heisenberg Fellow.
