A note on the neutrino mass implications of the K2K experiment
Suvadeep Bose, Amitava Raychaudhuri
Abstract
The K2K experiment has presented the first results on the observation of numu. They show a depletion compared to the expectations and are consistent with neutrino oscillations with a mass-splitting in the range favoured by the Super-Kamiokande atmospheric neutrino measurements. Here we examine the extent by which the range of Delta m2 obtained from the K2K measurements can vary due to the uncertainties in the flux, cross-section, and detector efficiency.
