Generalized parton distributions and their singularities

Physical Review D, 2011
A new approach to building models of generalized parton distributions (GPDs) is discussed that is based on the factorized DD (double distribution) Ansatz within the single-DD formalism. The latter was not used before, because reconstructing GPDs from the forward limit one should start in this case with a very singular function f(β)/β rather than with ...

The generalized parton distributions of the nucleon in the NJL model based on the Faddeev approach

, 2005
We study the generalized parton distributions, including the helicity-flip ones, using Nambu-Jona-Lasinio model based on a relativistic Faddeev approach with `static approximation'.

On the role of soft and non-perturbative gluons in collinear parton densities and parton shower event generators

European Physical Journal C: Particles and Fields
The Parton Branching method offers a Monte Carlo solution to the DGLAP evolution equations by incorporating Sudakov form factors. In this approach, the Sudakov form factor can be divided into perturbative and non-perturbative components, with the non ...

Center-of-mass energy dependence of intrinsic- $$k_{\textrm{T}}$$ k T distributions obtained from Drell–Yan production

European Physical Journal C: Particles and Fields
The internal motion of partons inside hadrons has been studied through its impact on very low transverse momentum spectra of Drell–Yan (DY) pairs created in hadron-hadron collisions.
