A search for νμ oscillations in the Δm2 range 0.3–90 eV2

Abstract We have searched for ν μ oscillations by comparing the rates of ν gm charged-current interactions in two detectors located 130 and 885 m from the target, which was struck by a 9.2 GeV/ c proton beam from the CERN Proton Synchroton. No evidence for ν μ oscillations was found. At the 90% confidence level, Δm 2 values between 0.26 and 90 eV 2 are excluded for maximal mixing. The most restrictive limit on the neutrino mixing-angle parameter sin 2 2 θ is 0.053 at Δm 2 =2.5 eV 2 .

A Measurement of Differential Cross-Sections and Nucleon Structure Functions in Charged Current Neutrino Interactions on Iron

A high-statistics measurement of the differential cross-sections for neutrino-iron scattering in the wide-band neutrino beam at the CERN SPS is presented. Nucleon structure functions are extracted and theirQ2 evolution is compared with the predictions of quantum chromodynamics.

Measurement of neutrino and antineutrino structure functions in hydrogen and iron

The CDHS neutrino detector has been used to measure events originating in a tank of liquid hydrogen and in the iron of the detector. Total cross-sections, differential cross-sections, and structure functions are given for hydrogen and compared with those in iron. The measurements are in agreement with the expectations of the quark parton model. No significant differences indicative of nuclear binding effects in corresponding structure functions of protons and iron are observed. This may be of special interest in the case of the sea structure functions, since large differences are expected in some models.
