Measurement of the Ratio of Neutrino Total Cross Sections on Hydrogen and Deuterium in the Brookhaven 7-Ft. Bubble Chamber.

摘要

Charged current neutrino interactions obtained in hydrogen and deuterium as a function of charged track multiplicity are presented. The ratio of neutrino fluxes in the two exposures is obtained from the two samples of the reaction nu p implies mu exp -pi exp + . The ratio of total charged current cross sections on hydrogen and deuterium is thus obtained and presented as a function of neutrino energy. The result obtained for neutrino energies above 2GeV is:sigma (H sub 2 )/sigma (D sub 2 ) = 0.40 +- 0.10.
