Abstract

Recent measurements of CPT violation and Lorentz symmetry breaking in B0Bˉ0B^0-\bar{B}^0 mixing and Bs0Bˉs0B^0_s-\bar{B}^0_s 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 BB mesons at LHCb, the SME coefficients can be determined with high precision. The bounds on these coefficients are improved significantly compared to previous measurements.
