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…
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.…
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…
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…
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…
