We report here additional positive results of a search for muonless neutrino- and anti-neutrino-induced events using an enriched antineutrino beam and a muon identifier of relatively high geometric detection efficiency. The ratio of muonless to muon event rates is observed to be R=0.20±0.05. We observe no background derived from ordinary neutrino or antineutrino interactions that is capable of explaining the muonless signal.

Dependence of nu nucleus cross-sections on the mass number

Borer, K. ; Hahn, B. ; Hofer, H. ; et al.

High energy v -nucleus cross sections have been compared for Pb, Fe, Al and C as target nuclei, exposed to the CERN v -beam. The events with θ vμ < 29 0 and p μ ⪆ 1 GeV /c have rates in the ratio of the mass number of the nuclei. Also a restricted sample with q 2 ⪅ 0.1 (GeV/ c ) 2 and θ vμ < 5 0 does not reveal a theoretically predicted deviation from A -proportionality, although due to the limited statistical accuracy in this restricted sample an “ A 2 3 - contribution ” of several tenths cannot be excluded either.
