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…

New Spin Structure Constraints on Hyperfine Splitting and Proton Size
David Ruth, Karl Slifer, Jian-Ping Chen +9
The 1S hyperfine splitting in hydrogen is measured to an impressive ppt precision and will soon be measured to ppm precision in muonic hydrogen. The latter measurement will rely on…
