| (a) Distribution of the mass difference $\Delta m$ for $\dstaro\mu$ combinations of opposite charge (points) and same charge (dashed line). The solid line shows the result of the fit described in the text. (b)~Distribution~of the opposite charge $\dstaro\mu$ invariant mass, for mass combinations within $\pm3\sigma$ of the $\Delta m$ peak, without applying the invariant mass cut described in the text. The measured distribution is compared with the MC simulation, including the contribution of different sources of signal. The hashed bands show the MC statistical uncertainty.Caption not extracted |

| Differential cross section for $\dsmucross X$ production as a function of (a) $\pT$ and (b) $|\eta|$ of the $b$-hadron, in the fiducial kinematical region $\pT(\dstarp)>4.5\GeV, \pT(\mu^-)>6\GeV, |\eta(\dstarp)|<2.5$ and $|\eta(\mu^-)|<2.4$. The measurement is compared with the theoretical predictions, as described in the text. The inner error bars of the data points are statistical uncertainties, the outer are statistical+total systematic uncertainties.Caption not extracted |

| Differential cross section for $\Bhadrn$ production as a function of (a) $\pT$ and (b) $|\eta|$ of the $b$-hadron, in the fiducial kinematical region $\pT(\Bhadrn)>9\GeV, |\eta(\Bhadrn)|<2.5$. The measurement is compared with the theoretical predictions, as described in the text. The inner error bars of the data points are statistical uncertainties, the outer are statistical+total systematic uncertainties.Caption not extracted |
