Abstract

Neutrino interactions with two muons in the final state have been studied using the Fermilab narrow band beam. A sample of 18vµ like sign dimuon events withPµ>9 GeV/c yields 6.6±4.8 events after backgroud subtraction and a prompt rate of (1.0±0.7)×10-4 per single muon event. The kinematics of these events are compared with those of the non-prompt sources. A total of 437vµ and 31 " opposite sign dimuon events withPµ>4.3 GeV/c are used to measure the strange quark content of the nucleon: " using a charm semileptonic branching ratio of (10.9±1.4)% extracted from measurements ine+e- collisions and neutrino emulsion data.

10. Nucleon structure functions from high energy neutrino interactions with iron and QCD results

Author

MacFarlane, D. B., Purohit, M. V., Messner, R. L., Novikoff, D. B., Blair, R. E., Sciulli, F. J., Shaevitz, M. H., Fisk, H. E., Fukushima, Y., Jin, B. N., Kerns, Q. A., Kondo, T., Rapidis, P. A., Segler, S. L., Stefanski, R. J., Theriot, D., Yovanovitch, D. D., Bodek, A., Coleman, R. N., Marsh, W. L., Fackler, O. D., and Jenkins, K. A.

Abstract

Nucleon structure functions obtained from neutrino and anti-neutrino scattering on iron nuclei at high energies (Ev=30 to 250 GeV) are presented. These results are compared with the results of other lepton-nucleon scattering experiments. The structure functions are used to test the validity of the Gross-Llewellyn-smith sum rule, which measures the number of valence quarks in the nucleons, and to obtain leading and second order QCD fits.

Abstract

We report on the characteristics of 9 bb pair events produced by a 600 GeV/c π- beam and detected in the hybrid emulsion spectrometer of Fermilab experiment E653. The measured lifetimes for samples of 12 neutral and 6 charged beauty hadrons are τb0 = 0.81+0.34+0.08-0.22-0.02 ps, and τb± = 3.84+2.73+0.80-1.36-0.16 ps.
