Superluminal Group Velocity of Neutrinos : Review, Development and   Problems
  The purpose of this paper is both to provide mathematical reinforcements to the paper [Mecozzi and Bellini : arXiv:1110.1253 [hep-ph]] by taking decoherence into consideration and to present some important problems related.   We claim that neutrinos have superluminality as a latent possibility.
