Supersymmetric extension of the Lorentz- andCPT-violating Maxwell-Chern-Simons model

Abstract: Focusing on gauge degrees of freedom specified by a 1+3 dimensions model hosting a Maxwell term plus a Lorentz and CPT non-invariant Chern-Simons-like contribution, 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. Furthermore, a non-polynomial generalization is presented.

“…Our conclusion supports the recent result of ref. [12] that Chern-Simons interactions require SUSY breaking. Moreover, by taking V ′ = ∂ m ∂ n V in (16), we conclude that the only dimension five operator that leads to E 3 -modification of the photon dispersion relation [4], Before summarizing our main findings we comment on some recent publications [13,14] that considered the construction of dimension three and four SUSY LV interactions for a (neutral) chiral superfield, which seems to be in conflict with the main results of this work.…”

“…One possible approach to this problem was presented by Belich et.al. [19], where the authors included extra fields depending on the Lorentz-breaking parameters, allowing the arising of the CPT-odd Lorentz-breaking terms in the supersymmetric Lagrangian. Another possibility is based on the Kostelecky-Berger construction [20] in which the main characteristic is the deformation of the SUSY algebra, allowing the arising of the CPT-even Lorentz-breaking terms.…”

“…Na literatura recente a proposta de quebra de simetria de Lorentzé realisada por um quadrivetor (p µ ou v µ ) proveniente da quebra espontânea de uma simetria interna [3,14], [15,16]. De maneira equivalente, as componentes deste quadrivetor, sob transformação de partícula, tem um comportamento escalar.…”
