Transverse-spin dependent energy-energy correlators in proton-proton collisions within the dihadron fragmentation framework

Zhong-Bo Kang, Andreas Metz, Daniel Pitonyak +1

We calculate energy-energy correlations for two hadrons produced inside a jet in transversely polarized proton-proton collisions. We make numerical predictions based on a simple mo…

Impact of Future Dihadron Production Measurements on the Transversity Distributions and Tensor Charges of the Nucleon

Yorgo Sawaya, Christina Cocuzza, Gregory Matousek +6

We assess the impact of future measurements of dihadron production in semi-inclusive deep-inelastic scattering from the CLAS12 and proposed SoLID experiments at Jefferson Lab, as w…

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…

Simplified approach to extracting nucleon transversity in collinear factorization using near-side energy-energy correlators

Zhong-Bo Kang, Andreas Metz, Daniel Pitonyak +1

We develop a novel strategy for accessing the transversity parton distribution function (PDF) of the nucleon within collinear factorization using near-side energy-energy correlator…

Dihadron fragmentation framework for near-side energy-energy correlators

Zhong-Bo Kang, Andreas Metz, Daniel Pitonyak +1

We establish an approach to analyze the free hadron and transition (nonperturbative) regions of near-side energy-energy correlators (EECs) based on dihadron fragmentation functions…

Transverse single-spin asymmetries in SIDIS as a direct probe of quark-gluon-quark longitudinal momentum structure

Michael Harris, Jacob Marsh, Daniel Pitonyak +4

Transverse single-spin asymmetries in the semi-inclusive deep-inelastic production of isolated photons (SIDIS), , provide an unprecedented opportunity t…
