Abstract

We propose a new formula to determine the first moment of difference between polarized ū and d̄-quarks in the nucleon from the Drell-Yan processes in collisions unpolarized hadrons with longitudinally polarized nucleons by measuring outgoing lepton helicities. Numerical calculation for this formula is done for a case of Δū = Δd̄.
