Abstract [en]

We present the first search for CPT-violating effects in the mixing of B-s(0) 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-s(0) -> mu 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 Delta a(perpendicular to) < 1.2 x 10(-12) GeV and (-0.8 < Delta a(T) - 0.396 Delta a(Z) < 3.9) x 10(-13) GeV.
