Abstract

The NOMAD Collaboration presents a study of opposite sign dimuon events in the framework of Leading Order QCD. A total of 2714 neutrino- and 115 antineutrino-induced opposite sign dimuon events with E(μ1),E(μ2) > 4.5 GeV, 15 < E(ν) < 300 GeV and Q² > 1 (GeV/c)² are observed in the Front-Calorimeter of NOMAD during the 1995 and 1996 runs. The analysis and for the average semileptonic branching ratio of yields a value for the charm quark mass of m(c)=1.3_-0.3-0.3/^+0.3+0.3 GeV/c² and for the average semileptonic branching ratio of B(c) = 0.095_-0.007-0.013/^+0.007+0.014. The ratio of the strange to non-strange sea in the nucleon is measured to be κ = 0.48 _-0.07-0.12/^+0.09+0.17. The measured rate of charm-induced dimuon relative to single muon, as a function of neutrino energy, is consistent with the slow rescaling hypothesis of heavy quark production.

N2 - The NOMAD Collaboration presents a study of opposite sign dimuon events in the framework of Leading Order QCD. A total of 2714 neutrino- and 115 antineutrino-induced opposite sign dimuon events with E(μ1),E(μ2) > 4.5 GeV, 15 < E(ν) < 300 GeV and Q2 > 1 (GeV/c)2 are observed in the Front-Calorimeter of NOMAD during the 1995 and 1996 runs. The analysis and for the average semileptonic branching ratio of yields a value for the charm quark mass of m(c)=1.3-0.3-0.3/+0.3+0.3 GeV/c2 and for the average semileptonic branching ratio of B(c) = 0.095-0.007-0.013/+0.007+0.014. The ratio of the strange to non-strange sea in the nucleon is measured to be κ = 0.48 -0.07-0.12/+0.09+0.17. The measured rate of charm-induced dimuon relative to single muon, as a function of neutrino energy, is consistent with the slow rescaling hypothesis of heavy quark production.
