The excess of highest energy solar-neutrino events recently observed by Superkamiokande can be in principle explained by anomalously high hep-neutrino flux Φ ν (hep). Without using SSM calculations, from the solar lumi-nosity constraint we derive that Φ ν (hep)/S 13 cannot exceed the SSM estimate by more than a factor three. If one makes the additional hypothesis that hep neutrino production oc...

Our goal in this paper is to examine the discovery potential of laboratory experiments searching for the oscillation νµ(νe) → ντ , in the light of recent data on solar and atmospheric neutrino experiments, which we analyse together with the most restrictive results from laboratory experiments on neutrino oscillations in a four-neutrino framework.

If the low energy cross section for He + p → He + e + νe, the ‘hep’ reaction, is ∼ > 20 times larger than the best (but uncertain) theoretical estimates, then this reaction could significantly influence the electron energy spectrum produced by solar neutrino interactions and measured in the SuperKamiokande, SNO, and ICARUS experiments. We compare predicted energy spectra for different assumed h...
