Collins effect in pion-in-jet production in polarized and collisions
Carlo Flore, Umberto D'Alesio, Marco Zaccheddu
We study Collins azimuthal asymmetries for pion-in-jet production in polarized proton-proton and lepton-proton collisions. We adopt a hybrid transverse momentum dependent approach,…
Collins asymmetries for pion-in-jet production in polarized collisions at the EIC
Umberto D'Alesio, Carlo Flore, Marco Zaccheddu
We study Collins azimuthal asymmetries for pion-in-jet production in polarized lepton-proton collisions, extending previous analyses of polarized scattering to a complementary…
TMDs in the Lens of Generative AI: A Pixel-Based Approach to Partonic Imaging
Marco Zaccheddu, Leonard Gamberg, Wally Melnitchouk +4
This work introduces a novel, nonparametric pixel-based framework for the Bayesian inference and imaging of transverse momentum dependent (TMD) parton distributions. The methodolog…
Frascati 22 GeV Workshop Summary
A. Accardi, P. Achenbach, A. Afanasev +103
This document summarizes the outcomes of the "Science at the Luminosity Frontier: Jefferson Lab at 22 GeV" workshop, held at the INFN Laboratori Nazionali di Frascati in December 2…
Collins function for pion-in-jet production in polarized collisions: a test of universality and factorization
Umberto D'Alesio, Carlo Flore, Marco Zaccheddu
We present an updated study of the Collins azimuthal asymmetries for pion-in-jet production in polarized collisions. To this aim, we employ a recent extraction of the transver…
Kernel methods for evolution of generalized parton distributions
A. Freese, D. Adamiak, I. Cloët +4
Generalized parton distributions (GPDs) characterize the 3-dimensional structure of hadrons, combining information about their internal quark and gluon longitudinal momentum distri…
