Remarks on the Causality, Unitarity and Supersymmetric Extension of the Lorentz and CPT-Violating Maxwell-Chern-Simons Model
نویسنده
چکیده
The gauge-invariant Chern-Simons-type Lorentzand CPT-breaking term is here re-assessed and issues like causality, unitarity, spontaneous gauge-symmetry breaking are investigated. Moreover, we obtain a minimal extension of such a system to a supersymmetric environment. We comment on resulting peculiar self-couplings for the gauge sector, as well as on background contribution for gaugino masses.

Remarks on Lorentz and CPT Violation in Field Theory
The possibility of breaking Lorentz and CPT symmetries has been considered in several different contexts [1–6]. Most of them were dedicated to the extended quantum electrodynamics (QED) sector of the extended standard model (see e.g. Ref. [2, 3]). The initial motivation for consideration of Lorentz violation came from string theory [7, 8]. Its basic idea is that interactions in the underlying t...
متن کاملAspects of Causality and Unitarity and Comments on Vortex-like Configurations in an Abelian Model with a Lorentz-Breaking Term
The gauge-invariant Chern-Simons-type Lorentzand CPT-breaking term is here reassessed and a spin-projector method is adopted to account for the breaking (vector) parameter. Issues like causality, unitarity, spontaneous gauge-symmetry breaking and vortex formation are investigated, and consistency conditions on the external vector are identified.

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.

Using the Fock-Schwinger proper time method, we calculate the induced Chern-Simons term arising from the Lorentzand CPT-violating sector of quantum electrodynamics with a bμψ̄γ γ5ψ term. Our result to all orders in b coincides with a recent linear-in-b calculation by Chaichian et al. [hepth/0010129 v2]. The coincidence was pointed out by Chung [Phys. Lett. B461 (1999) 138] and Pérez-Victoria [Ph...
متن کاملVacuum Čerenkov Radiation in Maxwell-chern-simons Electrodynamics
In recent years the so-called Standard-Model Extension (SME) has provided a convenient framework for studying minute Lorentz and CPT violations that may be low-energy signatures for Planck-scale physics. In this work we will study a subsector of the SME describing pure electrodynamics, where Maxwell theory has been modified with Chern–Simons-like term in the Lagrangian parametrized by dimension...
