A quantum field model for tachyonic neutrinos with Lorentz symmetry breaking
Marek J. Radzikowski
A quantum field model for Dirac-like tachyons respecting a frame-dependent interpretation rule, and thus inherently breaking Lorentz invariance, is defined. It is shown how the usu…
Stable, Renormalizable, Scalar Tachyonic Quantum Field Theory with Chronology Protection
Marek J. Radzikowski
We use microlocal arguments to suggest that Lorentz symmetry breaking must occur in a reasonably behaved tachyonic quantum field theory that permits renormalizability. In view of t…
Phase Space Factor for Two-Body Decay if One Product is a Stable Tachyon
Marek J. Radzikowski
We calculate the phase space factor for a two-body decay in which one of the products is a tachyon. Two threshold conditions, a lower and an upper one, are derived in terms of the…
Quantum Field Theory on Spacetimes with a Compactly Generated Cauchy Horizon
Bernard S. Kay, Marek J. Radzikowski, Robert M. Wald
We prove two theorems which concern difficulties in the formulation of the quantum theory of a linear scalar field on a spacetime, (M,g_{ab}), with a compactly generated Cauchy hor…
