Probing polarized valence quark distributions in W⁻-boson production

الأصل · EN

While EMC-SMC-E142 data sheds new light on the behavior of polarized parton distributions at small and intermediate x, it may be also interesting to study valence quark polarizations at large x, where spectator quark counting rules and Carlitz-Kaur type models predict different behavior for down quark polarizations. The article examines the possibility of testing the ratio Δdᵥ(x)/dᵥ(x) at x→ 1 in the inclusive production of W⁻-bosons.
