چکیده
We consider an extended QED with the addition of a dimension-five Lorentz-breaking coupling between spinor and gauge fields, involving pseudo-tensor $\kappa^{\mu\nu\lambda\rho}$. The specific form Lorentz violating considered by us have been suggested in other works, some its consequences at classical level were already studied. Here, we investigate this violation quantum level, evaluating one loop corrections to field two-point function, both zero finite temperature. relate terms that are generated photon sector Standard Model Extension, discussing possibility establishing experimental bounds on $k^{\mu\nu\rho\sigma}$. From dispersion relations resulting theory, discuss consistency from causality viewpoint.

Lorentz-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...
متن کاملRadiatively Induced Lorentz-Violating Photon Masses
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-energy is known to contain terms that violate gauge invariance. Previously, this has been treated as a pathology, but it is also possible to take the gauge noninvariant terms at face value. These terms then make Lore...
متن کاملSpontaneous breaking of Lorentz symmetry in (2+1)-dimensional QED
The phase diagram of quantum electrodynamics in three space-time dimensions as a function of fermion flavor number N exhibits two well-known phases: at large N > N c the system is in a conformal state with anomalous exponents, while for small N < N c the fermions are expected to develop a dynamical mass due to spontaneous chiral symmetry breaking. Using expansion near the lower critical dimensi...
متن کاملLorentz - and CPT - Violating Extension of the Standard Model
The formulation and some experimental implications of a general Lorentz-violating extension of the standard model are reviewed. The theory incorporates both CPT-preserving and CPT-breaking terms. It is otherwise a conventional quantum field theory, obtained under the assumption that Lorentz symmetry is spontaneously broken in an underlying model. The theory contains the usual standard-model gau...
متن کاملThe Lorentz-violating extension of the Standard Model
Quantum-gravity effects are expected to be suppressed by the Planck mass. For experimental progress it is therefore important to identify potential signatures from Planck-scale physics that are amenable to ultrahigh-precision tests. It is argued that minuscule violations of Lorentz and CPT symmetry are candidate signals. In addition, theoretical and experimental aspects of the Standard-Model Ex...
