dc.description.abstract | Using data collected with the D0 detector at the Fermilab Tevatron Collider, corresponding to 5:3 fb-1
of integrated luminosity, we search for violation of Lorentz invariance by examining the tt production
cross section in lepton + jets final states. We quantify this violation using the standard-model extension
framework, which predicts a dependence of the tt production cross section on sidereal time as the
orientation of the detector changes with the rotation of the Earth. Within this framework, we measure
components of the matrices (CQ)μν33 and (Cu)μν33 containing coefficients used to parametrize violation of
Lorentz invariance in the top quark sector. Within uncertainties, these coefficients are found to be
consistent with zero. | en_US |
