Δm² Limits from R(Eν)

الأصل · EN

A lower bound on Δm² for atmospheric neutrino oscillations can be obtained from the global value of R at a given energy. This bound may be more reliable than one based on the observed isotropy. Some global values of R imply an anisotropy in the neutrino flux that may, or may not be manifest in the observed neutrino interactions. A limit of Δm²>0.0077 eV² is easily obtained. Much higher mass scales are implied by the reported energy independence and magnitude of R
