Description
The longitudinal spin structure of the proton is studied with the COMPASS experiment using SIDIS data collected with a longitudinally polarized NH$3$ target and positive muon beams of 160 GeV/$c$ in 2007 and 200 GeV/$c$ in 2011. The analysis focuses on the double-spin asymmetry $A{LL}$, providing access to the spin-dependent structure function $g_1$, together with azimuthal asymmetries sensitive to longitudinal spin-dependent effects in SIDIS.
