Superluminal group velocity through near-maximal neutrino oscillations
Recently it was suggested that the observation of superluminal neutrinos by
the OPERA collaboration may be due to group velocity effects resulting from
close-to-maximal oscillation between neutrino mass eigenstates, in analogy to
known effects in optics. We show that superluminal propagation does occur
through this effect for a series of very narrow energy ranges, but this
phenomenum cannot explain the OPERA measurement.Comment: Reworking includes corrections due to finite width of the wave
packet, further references, and comments on other corrections, causality, the
new OPERA results, and why the size of neutrino wave packet provides
important constraint
