Polarized light-flavor antiquarks from Drell-Yan processes of h+\vec{N}\to\vec{l^{+-}} + l^{-+} + X

H. Kitagawa, Y. Sakemi, T. Yamanishi

We propose a formula to determine the first moment of difference between the polarized $\bar{u}$- and $\bar{d}$-quarks in the nucleon, {\it i.e.} $\Delta \bar{u}-\Delta \bar{d}$ from the Drell-Yan…
