Measurements of CPT Violation at LHCb
Abstract
Recent measurements of CPT violation and Lorentz symmetry breaking in B0-B0 mixing and B0s-B0s mixing, obtained from data taken by the LHCb experiment, are highlighted. The results are expressed in terms of the Standard-Model Extension (SME) coefficients, which incorporate both CPT and Lorentz violation. Due to the large boost of the B mesons at LHCb, the SME coefficients can be determined with high precision. The bounds on these coefficients are improved significantly compared to previous measurements.
