A New Low Measurement of the Proton's Spin Structure Function from Longitudinal & Transverse Polarized Data
D. Ruth, R. Zielinski, C. Gu +94
The proton's spin structure has proven to be far more complicated than was originally believed, and has been the subject of a number of experimental investigations. %Early measurem…
Addendum to multiplicities of charged pions, kaons and unidentified charged hadrons on an isoscalar target measured by COMPASS Collaboration
The COMPASS Collaboration
The COMPASS Collaboration has recently published an article "Multiplicities of positive and negative pions, kaons, and unidentified hadrons from deep-inelastic scattering of muons…
Dihadron Transverse-Spin Asymmetries in Muon-Deuteron Deep-Inelastic Scattering
G. D. Alexeev, M. G. Alexeev, C. Alice +168
In 2022, the COMPASS collaboration performed semi-inclusive measurements of deep-inelastic muon-scattering on a transversely polarised deuteron (6LiD) target. From these data, tran…
Threshold Photoproduction as a Probe of Nuclear Gluon Structure
J. R. Pybus, D. Dutta, H. Gao +83
The nuclear EMC effect is the observation that quark distributions in bound nucleons experience significant modification at large relative to free nucleons. Despite decades of…
Measurement of the helicity-dependent response in quasi-elastic proton knockout from
Tim Kolar, Iris Sabo-Napadensky, Patrick Achenbach +34
The role of the electron-helicity-dependent cross-section term and the structure function in the quasi-elastic process was studied. The…
