| Resumen |
We present the first search for CPT -violating effects in the mixing of B 0 s mesons using the full Run II data set with an integrated luminosity of 10.4 fb−1 of proton-antiproton collisions collected using the D0 detector at the Fermilab Tevatron Collider. We measure the CPT -violating asymmetry in the decay B 0 s →μ ± D ± s as a function of celestial direction and sidereal phase. We find no evidence for CPT -violating effects and place limits on the direction and magnitude of flavor-dependent CPT - and Lorentz-invariance violating coupling coefficients. We find 95% confidence intervals of Δa ⊥ <1.2×10 −12 GeV and (−0.8<Δa T −0.396Δa Z <3.9)×10 −13 GeV. |
