Double-longitudinal spin asymmetry in single-inclusive lepton scattering at NLO
Double-longitudinal spin asymmetry in single-inclusive lepton scattering at NLO
The authors compute full next-to-leading order corrections (NLO) to the double longitudinal spin asymmetry in lepton nucleon collisions producing a jet or hadron. Comparison with data shows that discrepancies with the predictions remain, motivating further work on both the theory and experimental fronts.
