The COMPASS Collaboration
The COMPASS experiment at the CERN SPS has studied the diffractive dissociation of negative pions into the π−π−π+ final state using a 190 GeV/c pion beam hitting a lead target. A partial waveExpand

First Measurement of Transverse-Spin-Dependent Azimuthal Asymmetries in the Drell-Yan Process.
The first measurement of transverse-spin-dependent azimuthal asymmetries in the pion-induced Drell-Yan (DY) process is reported. We use the CERN SPS 190  GeV/c π^{-} beam and a transversely polarizedExpand
