Description
We report on recent measurements using $B$-meson decays in $10.4\ \rm fb^{−1}$ of proton-antiproton collisions collected by the D0 detector during Run II at the Fermilab Tevatron Collider. We present the first search for exclusive CPT-violating effects in the mixing of $B_s^0$ mesons. We find no evidence for the CPT-violating effects tested and place limits on CPT- and Lorentz-invariance violating coupling coefficients, $\Delta a_\mu$. We also present the first measurement of the direct CP-violating charge asymmetry in $B^\pm$ mesons decaying to $\mu^\pm D^{0} X$ where the $D^0$ decays to $K^+ \pi^-$.
