Improving constraints on gluon spin-momentum correlations in transversely polarized protons via midrapidity open-heavy-flavor electrons in p? plus p collisions at psffi=200 GeV

N. J. Abdulameer et al.

Summary: Polarized proton-proton collisions provide an opportunity to understand the structure of the proton by constraining gluon spin-momentum correlations. Midrapidity open-heavy-flavor production at 200 GeV is dominated by gluon-gluon fusion, offering heightened sensitivity to gluon dynamics. Measurements of transverse single-spin asymmetries of positrons and electrons from heavy-flavor hadron decays are used to extract explicit constraints on gluon correlators.

J/ψ polarization in semi-inclusive DIS at low and high transverse momentum

Umberto D'Alesio et al.

Summary: This study investigates the polar and azimuthal decay angular distributions of J/ψ mesons produced in semi-inclusive, deep-inelastic electron-proton scattering. The research adopts the framework of nonrelativistic QCD and focuses on the cos 2 phi azimuthal decay asymmetry as well as proposes a novel experiment for the extraction of an unknown parton density. By determining the perturbative tails of the shape functions and finding them to be independent of the J/ψ polarization, the study contributes to a better understanding of the quarkonium formation mechanism.

Probing Gluon Spin-Momentum Correlations in Transversely Polarized Protons through Midrapidity Isolated Direct Photons in p ↑ + p Collisions at √s=200 GeV

U. A. Acharya et al.

Summary: Studying spin-momentum correlations in hadronic collisions provides insight into the three-dimensional structure of protons, and measuring direct photons is a clean probe of initial-state spin-momentum correlations within the proton. These results from RHIC represent a significant improvement in uncertainty compared to prior measurements and constrain gluon spin-momentum correlations in transversely polarized protons.
