Vacuum Cherenkov radiation and photon triple-splitting in a Lorentz-noninvariant extension of quantum electrodynamics
We consider a CPT–noninvariant scalar model and a modified version of quantum electrodynamics with an additional photonic Chern–Simons-like term in the action. In both cases, the Lorentz violation traces back to a spacelike background vector. The effects of the modified field equations and dispersion relations on the kinematics and dynamics of decay processes are discussed, first for the simple...
متن کاملVacuum photon splitting in Lorentz-violating quantum electrodynamics.
Radiative corrections arising from Lorentz violation in the fermion sector induce a nonzero amplitude for vacuum photon splitting. At one loop, the on-shell amplitude acquires both CPT-even and CPT-odd contributions forbidden in conventional electrodynamics.
متن کاملOn the Vacuum Cherenkov Radiation in Noncommutative Electrodynamics and the Elusive Effects of Lorentz Violation
We show that in the framework of noncommutative classical electrodynamics Cherenkov radiation is permitted in vacuum and we explicitly compute its spectrum at first order in the noncommutative parameter. We discuss the phenomenological impact of the merge of this new analysis with the old results of the substantial modification to the spectrum of the synchrotron radiation obtained in [1]. We pr...
متن کاملPhoton decay in a CPT-violating extension of quantum electrodynamics
We consider the process of photon decay in quantum electrodynamics with a CPTviolating Chern–Simons-like term added to the action. For a simplified model with only the quadratic Maxwell and Chern–Simons-like terms and the quartic Euler– Heisenberg term, we obtain a nonvanishing probability for the decay of a particular photon state into three others.
متن کاملCherenkov radiation in a photon gas
It is well-known that a charged particle moving with constant velocity in vacuum does not radiate. In a medium the situation can be different. If the so called Cherenkov condition is satisfied, i.e. the particle velocity exceeds the phase speed in the medium, the particle will radiate. We show that a charge moving with a constant velocity in a gas of photons emits Cherenkov radiation, even in t...
