Description

From an analysis of 2275 nu-barp → μ++X0 events at an average Q2 of 4.5 GeV2, there are presented the first measurements, up to one undetermined overall normalization constant, of the x dependence of the proton structure functions using antineutrinos, and of the u and d-bar+s-bar quark distributions. Our result for u (x) is in good agreement with models based on fits to electron and muon scattering data. With u (x) normalized to those models the absolute antiquark momentum distribution x[d-bar (x)+s-bar (x)] in the proton is determined
