Abstract: A quantum field model for Dirac-like tachyons respecting a frame-dependentinterpretation rule, and thus inherently breaking Lorentz invariance, isdefined. It is shown how the usual paradoxa ascribed to tachyons, instabilityand acausality, are resolved in this model, and it is argued elsewhere thatLorentz symmetry breaking is necessary to permit perturbative renormalizabilityand causality. Elimination of negative-normed states results in onlyleft-handed particles and right-handed antiparticles, suitable for describingthe neutrino. In this context the neutron beta decay spectrum is calculatednear the end point for large, but not ultrarelativistic preferred frame speed,assuming a vector weak interaction vertex.
