Abstract

From the analysis of 5630v_υ and of 1372v_π charged current interactions, obtained in the BEBC bubble chamber filled with deuterium and exposed to the CERN wide band antineutrino beam, the ratios of cross section on neutron and photon targets have been measured and found to be R σν)/σv_p = 0.51 ± 0.01 (±0.03), and R σ(ν_n)/σ(v_p) = 22.2 ± 0.12 (±0.25) The dependence of these ratios on the x scaling variable shows, in a direct way, that the momentum distribution of the majority quark, u_p(x) = d_n(x), is broader than that of the minority quark, u_n(x) = d_p(x).

N2 - From the analysis of 5630vυ and of 1372vπ charged current interactions, obtained in the BEBC bubble chamber filled with deuterium and exposed to the CERN wide band antineutrino beam, the ratios of cross section on neutron and photon targets have been measured and found to be R σν)/σvp = 0.51 ± 0.01 (±0.03), and R σ(νn)/σ(vp) = 22.2 ± 0.12 (±0.25) The dependence of these ratios on the x scaling variable shows, in a direct way, that the momentum distribution of the majority quark, up(x) = dn(x), is broader than that of the minority quark, un(x) = dp(x).
