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.

European Physical Journal C: Particles and Fields, 2020 Generalized transverse momentum dependent parton distributions (GTMDs), as mother funtions of transverse momentum dependent parton distributions (TMDs) and generalized parton distributions (GPDs), encode the most general parton structure of hadrons.

Intrinsic bottom and its impact on heavy new physics at the LHC
EPJ Web of Conferences, 2016 Heavy quark parton distribution functions (PDFs) play an important role in several Standard Model and New Physics processes. Most analyses rely on the assumption that the charm and bottom PDFs are generated perturbatively by gluon splitting and do not ...

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

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

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.

A new generation of simultaneous fits to LHC data using deep learning
Journal of High Energy Physics, 2022 We present a new methodology that is able to yield a simultaneous determination of the Parton Distribution Functions (PDFs) of the proton alongside any set of parameters that determine the theory predictions; whether within the Standard Model (SM) or ...

An analysis of polarized parton distribution functions with nonlinear QCD evolution equations
Nuclear Physics B, 2022 We present the polarized parton distribution functions from a QCD analysis of the worldwide polarized deep inelastic scattering data, based on the dynamical parton distribution model.

Double parton distributions in the pion from lattice QCD
Journal of High Energy Physics, 2021 We perform a lattice study of double parton distributions in the pion, using the relationship between their Mellin moments and pion matrix elements of two local currents. A good statistical signal is obtained for almost all relevant Wick contractions. We
