Prompt neutrinos and oscillations with mass differences of cosmological relevance

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

Prompted by cosmological considerations, a scenario is considered in which the most massive neutrino has a massm ν≲25 eV while the other neutrinos are much lighter. The possibility of oscillations characterized by Δm 2≲m ν2 is examined, with the conclusion thatν e↔ν x oscillations (x≠μ and possiblyx=τ) with sizeable mixing angles are not just allowed but in fact rather strongly indicated by the existing data on prompt neutrinos. The best values for the oscillation parameters Δm 2=(377±27±7) eV2, sin22α=0.48±0.10±0.05 are not in serious conflict with any of the existing limits.
