Affirmative, I seem to have reached a reference citation impasse regarding the tensor field functions integration of [math]\Lambda^{\mu}_{\alpha}[/math] and [math]\Lambda^{\nu}_{\beta}[/math]. All of the references that have been cited do not demonstrate a functions integration past this initial point for a tensor field. Is this approach at least mathematically and symbolically correct to this point? Any citations or recommendations? Any discussions and/or peer reviews about this specific topic thread?

This is true for the Compton equation, where a mass-less particle is scattering from a mass particle. However, in equation [math](6)[/math], the energy terms for [math]E[/math] represent the total energy of a mass particle, which includes its rest mass plus kinetic energy. I should have been more clear about that equation description and will include the total energy description in the next revision, hence peer review. If I understand this inelastic scattering correctly, when a lighter particle scatters from a heavier particle, as total kinetic energy is increased, then more kinetic energy is absorbed by the recoiling heavier particle and less kinetic energy is carried away by the lighter particle. So, the limit of equations [math](12)[/math] and [math](13)[/math] as kinetic energy approaches infinity, should be the rest mass of the neutrino.
