Evolution and interpolation of double parton distributions using Chebyshev grids [PDF]
European Physical Journal C: Particles and Fields, 2023 Double parton distributions are the nonperturbative ingredients needed for computing double parton scattering processes in hadron–hadron collisions. They describe a variety of correlations between two partons in a hadron and depend on a large number of ...

Parton interpretation and twist-4 parton distributions
Physics Letters B, 2021 Through explicit examples we show that twist-4 parton distributions have no parton interpretation in the sense that parton or partons inside a hadron can carry the momentum fraction x of the hadron with x>1 or x1.

Nuclear parton distributions [PDF]
EPJ Web of Conferences, 2017 We review a microscopic model of the nuclear parton distribution functions, which accounts for a number of nuclear effects including Fermi motion and nuclear binding, nuclear meson-exchange currents, off-shell corrections to bound nucleon distributions ...

Pion generalized parton distributions and light-front wave functions in the Nambu–Jona-Lasinio model
Nuclear Physics B, 2021 Pion generalized parton distributions and light-front wave functions are investigated in the framework of Nambu–Jona-Lasinio model. The properties of pion generalized parton distributions and light-front wave functions are examined separately. Proceeding

Collinear matching for next-to-leading power transverse-momentum distributions
Physics Letters B, 2023 Phenomenological studies of transverse momentum dependent (TMD) parton distributions rely on the expansion in small values of the transverse separation of fields, where TMD parton distributions match onto collinear parton distribution functions.

ρ meson GPDs and IPDs with a light-front constituent quark model [PDF]
EPJ Web of Conferences, 2019 We investigate the ρ meson unpolarized Generalized Parton Distributions based on a Light-Front Constituent Quark Model. Moreover, by employing a Gaussian form wave packet, we apply the obtained generalized parton distributions to get the Impact Parameter

PARTONIC INTERPRETATION OF GENERALIZED PARTON DISTRIBUTIONS [PDF]
International Journal of Modern Physics: Conference Series, 2011 Dispersion relations have been applied to hard exclusive processes suggesting that generalized parton distributions can be fully determined from their values on a kinematical ridge. We show significant pitfalls associated that vitiate this approach. We suggest an improved treatment of this assumption.
