Pair Production Constraints on Superluminal Neutrinos Revisited
arXiv:1112.1090
Abstract
We revisit the pair creation constraint on superluminal neutrinos considered by Cohen and Glashow in order to clarify which types of superluminal models are constrained. We show that a model in which the superluminal neutrino is effectively light-like can evade the Cohen-Glashow constraint.
