Double-Spin Transverse Asymmetries in Drell-Yan Processes
arXiv:hep-ph/9702239 · doi:10.1103/PhysRevD.56.527
Abstract
We calculate the double-spin transverse asymmetries for the Drell-Yan lepton pair production in p-p and p-anti p collisions. We assume the transverse and the longitudinal polarization densities to be equal at a very small scale, as it is suggested by confinement model results. Using a global fit for the longitudinal distributions, we find transverse asymmetries of order of 10^-2 at most, in the accessible kinematic regions.
