  In this article an idea is presented, which allows for the explanation of
superluminal muon neutrinos. It is based on the introduction of a new
superluminal, massless gauge boson coupling to the neutrino only, but not to
other standard model particles. The model is discussed with regard to the
Supernova 1987 (SN 1987) velocity bound on electron antineutrinos and the
Cohen-Glashow constraint on superluminal neutrino propagation. The latter can
be circumvented if - within the framework of the model - a sterile neutrino
mixing with the active neutrino mass eigenstates is introduced. The suggestion
of a sterile neutrino accounting for superluminal neutrinos has already been
proposed in several papers. It is possible to choose mixing angles with the
sterile neutrino sector such that the model respects both the SN 1987 bound and
the muon neutrino travels superluminally.
