dc.description.abstractUsing 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
