Lorentz-Violating Extension of the Standard Model

- D. Colladay, A. Kostelecký
- Physics
- 24 September 1998

In the context of conventional quantum field theory, we present a general Lorentz-violating extension of the minimal… Expand

Data Tables for Lorentz and CPT Violation

- A. Kostelecký, N. Russell
- Physics
- 1 January 2008

This work tabulates measured and derived values of coefficients for Lorentz and $CPT$ violation in the standard-model extension. Summary tables are extracted listing maximal attained sensitivities in… Expand

$CPT$ violation and the standard model

- D. Colladay, A. Kostelecký
- Physics
- 31 March 1997

Spontaneous CPT breaking arising in string theory has been suggested as a possible observable experimental signature in neutral-meson systems. We provide a theoretical framework for the treatment of… Expand

Gravity, Lorentz violation, and the standard model

- A. Kostelecký
- Physics
- 30 December 2003

The role of the gravitational sector in the Lorentz- and CPT-violating standard-model extension ~SME! is studied. A framework is developed for addressing this topic in the context of Riemann-Cartan… Expand

Analytical construction of a nonperturbative vacuum for the open bosonic string

- A. Kostelecký, R. Potting
- Physics
- 31 August 2000

Using analytical methods, a nonperturbative vacuum is constructed recursively in the field theory for the open bosonic string. Evidence suggests it corresponds to the Lorentz-invariant end point of… Expand

Signals for Lorentz violation in electrodynamics

- A. Kostelecký, M. Mewes
- Physics
- 20 May 2002

An investigation is performed of the Lorentz-violating electrodynamics extracted from the renormalizable sector of the general Lorentz- and CPT-violating standard-model extension. Among the… Expand

Electrodynamics with Lorentz-violating operators of arbitrary dimension

- A. Kostelecký, M. Mewes
- Physics
- 1 May 2009

The behavior of photons in the presence of Lorentz and CPT violation is studied. Allowing for operators of arbitrary mass dimension, we classify all gauge-invariant Lorentz- and CPT-violating terms… Expand

Signals for Lorentz violation in post-Newtonian gravity

- Q. Bailey, A. Kostelecký
- Physics
- 9 March 2006

The pure-gravity sector of the minimal standard-model extension is studied in the limit of Riemann spacetime. A method is developed to extract the modified Einstein field equations in the limit of… Expand

Matter-gravity couplings and Lorentz violation

- A. Kostelecký, J. Tasson
- Physics
- 21 June 2010

The gravitational couplings of matter are studied in the presence of Lorentz and $CPT$ violation. At leading order in the coefficients for Lorentz violation, the relativistic quantum Hamiltonian is… Expand

Stability, causality, and Lorentz and CPT violation

- A. Kostelecký, R. Lehnert
- Physics
- 7 December 2000

Stability and causality are investigated for quantum field theories incorporating Lorentz and CPT violation. Explicit calculations in the quadratic sector of a general renormalizable lagrangian for a… Expand
