Radiatively Induced Lorentz-Violating Photon Masses
B. Altschul
We examine the radiative corrections to an extension of the standard model containing a Lorentz-violating axial vector parameter. At second order in this parameter, the photon self…
Lorentz Violation and Faddeev-Popov Ghosts
B. Altschul
We consider how Lorentz-violating interactions in the Faddeev-Popov ghost sector will affect scalar QED. The behavior depends sensitively on whether the gauge symmetry is spontaneo…
Spontaneous Lorentz Violation and Nonpolynomial Interactions
B. Altschul, Alan Kostelecky
Gauge-noninvariant vector field theories with superficially nonrenormalizable nonpolynomial interactions are studied. We show that nontrivial relevant and stable theories have spon…
Nonunitary Quantum Theory with a Field Cutoff
B. Altschul
We consider a scalar quantum field theory, in which the interaction takes the form of a field cutoff; the energy diverges to infinity whenever the value of the field at some point…
Lorentz Violation and Synchrotron Radiation
B. Altschul
We consider the radiation emitted by an ultrarelativistic charged particle moving in a magnetic field, in the presence of an additional Lorentz-violating interaction. In contrast w…
