Signals of nonrenormalizable Lorentz and CPT violation at the LHC
We examine nonrenormalizable Lorentz- and CPT-violating effective operators applied to the quark sector of the Standard Model.

| Summary: | We examine nonrenormalizable Lorentz- and CPT-violating effective operators applied to the quark sector of the Standard Model. Using Drell-Yan events collected by the ATLAS and CMS Collaborations, several constraints are extracted from time-independent modifications of the cross section on the Z-boson pole. The sensitivity to time-dependent modifications is also estimated by simulating a sidereal-time analysis. Our results suggest a dedicated search can improve on constraints from deep inelastic scattering by up to three orders in magnitude. |
