Is There a High-y Anomaly in Antineutrino Interactions?

We have analyzed data taken in the CERN narrow-band neutrino and antineutrino beams with regard to the "high-y anomaly" observed by previous experiments at Fermilab. At neutrino energies between 30 and 200 GeV, the nu -bar and nu charged-current cross-section ratios and muon-inelasticity d...

Sumario:We have analyzed data taken in the CERN narrow-band neutrino and antineutrino beams with regard to the "high-y anomaly" observed by previous experiments at Fermilab. At neutrino energies between 30 and 200 GeV, the nu -bar and nu charged-current cross-section ratios and muon-inelasticity distributions disagree with the earlier results. In particular, there is no evidence for energy-dependent effects in the antineutrino data which constitute an important aspect of the alleged anomaly.
