We calculate the double-spin transverse asymmetries for the Drell-Yan lepton pair production in pp and pbar p collisions. We assume the transverse and the longitudinal polarization densities to be equal at a very small scale, as 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.

Abstract
We calculate the double-spin transverse asymmetries for the Drell-Yan lepton pair production in pp and pbar p collisions. We assume the transverse and the longitudinal polarization densities to be equal at a very small scale, as 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.File in questo prodotto:
