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.

Parton distributions for LO generators [PDF]
European Physical Journal C, 2008 We present a study of the results obtained combining LO partonic matrix elements with either LO or NLO partons distributions. These are compared to the best prediction using NLO for both matrix elements and parton 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

Polarized parton distributions [PDF]
Physical Review D, 1995 We analyze spin dependent parton distributions consistent with the most recent measurements of the spin dependent deep inelastic scattering structure functions and obtained in the framework of the spin dilution model. Predictions for the doubly polarised proton-proton Drell-Yan asymmetry, for the high $p_{T}$ photon production mechanism and $J ...

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

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 ...

Unintegrated parton distributions [PDF]
Physical Review D, 2001 We describe how to calculate the parton distributions $f_a(x, k_t^2, ^2)$, unintegrated over the parton transverse momentum $k_t$, from auxiliary functions $h_a(x, k_t^2)$, which satisfy single-scale evolution equations. The formalism embodies both DGLAP and BFKL contributions, and accounts for the angular ordering which comes from coherence effects ...

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.
