Abstract

Spin-averaged asymmetries in the azimuthal distributions of positive and negative hadrons produced in deep inelastic scattering were measured using the CERN SPS longitudinally polarised muon beam at 160GeV/c and a ⁶LiD target. The amplitudes of the three azimuthal modulations cos _φh, cos 2_φh and sin _φh were obtained binning the data separately in each of the relevant kinematic variables x, z or pTh and binning in a three-dimensional grid of these three variables. The amplitudes of the cos _φh and cos 2_φh modulations show strong kinematic dependencies both for positive and negative hadrons.
