Solar neutrino packet length

We wrote the following article summarizing our analysis of the 1976 S. Nussinov first neutrino packet length estimates for solar neutrinos. We conclude that the W CC boson virtual lifetime is the approximate bound, but that the packet length must nonetheless be consistent with the fact that flavor oscillations have been observed from sources at terrestrial reactors (and the basic requirement that a matter packet be at least as large as its de Broglie wavelength).
