AABOUD 2017E reports a measurement of charge asymmetry of A${}^{b}_{SL}$ = ($-25$ $\pm21$ $\pm19$) $ \times 10^{-3}$ in lepton + jets ${{\mathit t}}{{\overline{\mathit t}}}$ events in which a ${{\mathit b}}$-hadron decays semileptonically to a soft muon.

ABAZOV 2014 reports a measurement of like-sign dimuon charge asymmetry of A${}^{b}_{SL}$ = ($-4.96$ $\pm1.53$ $\pm0.72$) $ \times 10^{-3}$ in semileptonic ${{\mathit b}}$-hadron decays.

ABAZOV 2011U reports a measurement of like-sign dimuon charge asymmetry of ${{\mathit A}_{{{SL}}}^{b}}$ = ($-7.87$ $\pm1.72$ $\pm0.93$) $ \times 10^{-3}$ in semileptonic ${{\mathit b}}$-hadron decays.

ABAZOV 2010H reports a measurement of like-sign dimuon charge asymmetry of A${}^{b}_{SL}=(-9.57$ $\pm2.51$ $\pm1.46$) $ \times 10^{-3}$ in semileptonic ${\mathit {\mathit b}}$-hadron decays. Using the measured production ratio of ${{\mathit B}_{{{d}}}^{0}}$ and ${{\mathit B}_{{{s}}}^{0}}$, and the asymmetry of ${{\mathit B}_{{{d}}}^{0}}$ A${}^{d}_{SL}=(-4.7$ $\pm4.6$) $ \times 10^{-3}$ measured from ${{\mathit B}}$-factories, they obtain the asymmetry for ${{\mathit B}_{{{s}}}^{0}}$ as A${}^{s}_{SL}=(-14.6$ $\pm7.5$) $ \times 10^{-3}$.
