Contribution

It introduces calculations for Lorentz violation effects in top-quark processes at the LHC, expanding previous bounds to include gluon fusion production mechanisms.

Findings

Initial results on Lorentz violation effects in top-quark events at the LHC.

Extension of bounds on Lorentz-violating coefficients to gluon fusion processes.

Abstract

Lorentz and CPT violation can affect the rates for $t$-$\ol t$ production and decay. The Lorentz-violating coefficients in the Standard-Model Extension responsible for modifying the top-quark events have recently been bounded by the D0 Collaboration. To extend the analysis to the LHC the calculations need to be extended to include the gluon fusion production mechanism. Some of the first results of this program were presented at the Meeting.
