Measurement of the 3He spin-structure functions and of neutron (3He) spin-dependent sum rules at 0.035 ≤ Q2 ≤ 0.24 GeV2 (original) (raw)

The spin-structure functions g1 and g2, along with the spin-dependent partial cross-section σTT, have been extracted from the polarized cross-sections measured for the 3He(e,e)X reaction in the E97-110 experiment at Jefferson Lab. This study utilizes polarized electrons across a range of energies and angles to explore the nucleon spin structure, emphasizing the significance of the ∆ degree of freedom in spin observables. The precision of the extracted spin-structure functions and their comparison to chiral effective field theory predictions highlight key contributions to our understanding of nucleon spin at low momentum transfer.
