Based on experimental discovery that the mass-square of neutrino is negative,
a quantum equation for superluminal neutrino is proposed in comparison with
Dirac equation and Dirac equation with imaginary mass. A virtual particle may
also be viewed as superluminal one. Both the basic symmetry of space-time
inversion and the maximum violation of space-inversion symmetry are

Key words: ordinary neutrinos; neutrino mass and mixing; non-standard-model

Nothing can travel faster than light. Is this statement as true now as it
ever was? In 2000 there were two experiments showing superluminal propagation
of microwave or laser pulse Yet physicists believe that the law of physics
have remained intact . However, the experimental discovery of negative mass
square of neutrino in recent years
