Hadron azimuthal distributions and transverse spin asymmetries in DIS of leptons off transversely polarized targets from SMC

Abstract Azimuthal distributions of hadrons (mainly π + and π − ) produced in DIS off transversely polarized targets (proton and deuteron) are studied for the first time in SMC. From these azimuthal distributions, transverse single-spin asymmetries are derived. According to Collins (‘Collins effect’), the azimuthal distribution of the leading hadron might exhibit an symmetry which originates from the transverse polarization of the final quark.

Large gluon polarization from correlated high-pT hadron pairs in polarized electro-production

Abstract We propose to measure the polarized gluon distribution function ΔG ( η ) at η ≲0.2 via pseudo jet production in polarized fixed target lepton nucleon scattering at typical lepton beam energies of 200 GeV. The measurement of the spin-asymmetry for the production of correlated charge conjugated hadrons of opposite transverse momentum can be directly related to ΔG ( η ) through the photon-gluon fusion process. We also present a numerical analysis of the accuracy which can be obtained for different flavors and kinematics of the observed hadron pair.
