Photon decay in a CPT-violating extension of quantum electrodynamics
نویسنده
چکیده
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.

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 کاملHydrogen and Antihydrogen Spectroscopy for Studies of CPT and Lorentz Symmetry
A theoretical study of possible signals for CPT and Lorentz violation arising in hydrogen and antihydrogen spectroscopy is described. The analysis uses a CPTand Lorentz-violating extension of quantum electrodynamics, obtained from a general Lorentz-violating extension of the minimal standard model with both CPT-even and CPT-odd terms. Certain 1S-2S transitions and hyperfine Zeeman lines exhibit...
متن کاملLorentz-Violating Extension of the Standard Model
In the context of conventional quantum field theory, we present a general Lorentz-violating extension of the minimal SU(3) × SU(2)× U(1) standard model including CPT-even and CPTodd terms. It can be viewed as the low-energy limit of a physically relevant fundamental theory with Lorentz-covariant dynamics in which spontaneous Lorentz violation occurs. The extension has gauge invariance, energy-m...

The proof of one-loop renormalizability of the general Lorentz-and CPT-violating extension of quantum electrodynamics is described. Application of the renormalization-group method is discussed and implications for theory and experiment are considered.
