Query: Procedure with Massive Neutrinos for the Standard Model Processes with
  Negligible Lorentz Invariance Violation   For the electroweak interactions, the massive neutrino perturbative
kinematical procedure is developed in the massive neutrino Fock space; The
perturbation expansion parameter is the ratio of the neutrino mass to its
energy. This procedure, with the Pontecorvo-Maki-nakagawa-Sakata modified
electroweak Lagrangian, calculates the cross-sections with the new neutrino
energy projection operators in the massive neutrino Fock space, resulting in
the Standard Model mass-less flavor neutrino cross-sections, plus the Lorentz
non-invariant neutrino oscillation cross-sections which are proportional to the
squares of neutrino masses and, as such, practically unobservable in the
laboratory. This scheme reinforces the notion that the mass-less flavor
neutrino can be considered as the superposition of three massive neutrinos.
