Lorentz-Violating Extension of the Standard Model
@article{Colladay1998LorentzViolatingEO, title={Lorentz-Violating Extension of the Standard Model}, author={Don Colladay and Alan Kosteleck{\'y}}, journal={Physical Review D}, year={1998}, volume={58}, pages={116002} }
In the context of conventional quantum field theory, we present a general Lorentz-violating extension of the minimal $\mathrm{SU}(3)\ifmmode\times\else\texttimes\fi{}\mathrm{SU}(2)\ifmmode\times\else\texttimes\fi{}\mathrm{U}(1)$ standard model including $\mathrm{CPT}$-even and $\mathrm{CPT}$-odd 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…

Dimensional reduction of a Lorentz- and CPT-violating Maxwell-Chern-Simons model
- Physics
- 2003
Taking as a starting point a Lorentz and CPT noninvariant Chern-Simons-like model defined in $1+3$ dimensions, we proceed to realize its dimensional reduction to $D=1+2.$ One then obtains a new…

We investigate the Casimir effect, due to the confinement of a scalar field in a $D$-dimensional sphere, with Lorentz symmetry breaking. The Lorentz-violating part of the theory is described by an…

In this paper, we consider an electrodynamics of higher derivatives coupled to a Lorentz-violating background tensor. Specifically, we are interested in a dimension-five term of the CPT-odd sector of…
Photon sector analysis of Super and Lorentz symmetry breaking: effective photon mass, bi-refringence and dissipation

Within the standard model extension (SME), we expand our previous findings on four classes of violations of Super-Symmetry (SuSy) and Lorentz Symmetry (LoSy), differing in the handedness of the…
Thermal aspects of interacting quantum gases in Lorentz-violating scenarios

In this work, we study the interaction of quantum gases in Lorentz-violating scenarios considering both boson and fermion sectors. In the latter case, we investigate the consequences of a system…
Leading-order classical Lagrangians for the nonminimal standard-model extension

In this paper, we derive the general leading-order classical Lagrangian covering all fermion operators of the nonminimal Standard-Model Extension (SME). Such a Lagrangian is considered to be the…
Noncommutative gauge theory without Lorentz violation
- Mathematics, Physics

The most popular noncommutative field theories are characterized by a matrix parameter ${\ensuremath{\theta}}^{\ensuremath{\mu}\ensuremath{\nu}}$ that violates Lorentz invariance. We consider the…

We study the possibility of constructing Lorentz-violating supersymmetric quantum field theories under the assumption that these theories have to be described by Lagrangians which are renormalizable…
