Deep-neural-network extraction of unpolarized transverse-momentum-dependent parton distributions in space from Drell-Yan data
I. P. Fernando, D. Keller
We present a physics-informed deep-neural-network extraction of unpolarized transverse-momentum-dependent parton distribution functions (TMDPDFs) in impact-parameter space from Dre…
Evidence for Q-Dependent Nuclear Transverse-Momentum Redistribution Beyond Broadening from AI-driven analysis of p-Cu Drell-Yan
I. P. Fernando, D. Keller
We extract a target-side Cu transverse-momentum profile from fixed-target --Cu Drell--Yan data by holding a momentum-space proton reference fixed and training only an asymmetric…
Polarized Target Nuclear Magnetic Resonance Measurements with Deep Neural Networks
Devin Seay, Ishara P. Fernando, Dustin Keller
Continuous-wave Nuclear Magnetic Resonance (CW-NMR) operated in constant-current mode has served as a foundational technique for polarization measurement in solid-state dynamically…
Long Range Outlook for Short-Range Correlations
Nadia Fomin, Or Hen, Julian Kahlbow +99
Short range correlated (SRC) N N pairs are pairs of nucleons with high relative momentum (prel > kF where kF ~ 250 MeV/c is the Fermi momentum in medium to heavy nuclei) and lower…
Differentiable Principal-Value Inversion for Neural-Network Extraction of Generalized Parton Distributions
Dima Watkins, Ishara Fernando, Dustin Keller
We present a machine-learning method for the nonparametric extraction of generalized parton distributions (GPDs) from Compton form factors (CFFs) constrained by experimental data.…
Realizing the Scientific Program with Polarized Ion Beams at EIC
Grigor Atoian, Nigel Buttimore, Giuseppe Ciullo +67
Polarized ion beams at the Electron Ion Collider are essential to address some of the most important open questions at the twenty-first century frontiers of understanding of the fu…
Spin 1 Transverse Momentum Dependent Tensor Structure Functions in CLAS12
Jiwan Poudel, Alessandro Bacchetta, Jian-Ping Chen +6
We propose to analyze CLAS12 RG-C data to study the tensor transverse-momentum-dependent parton distribution functions (TMDs) on deuteron data. The deuteron is the lightest nucleus…
