Search for the rare decay $D^0 \to \mu^+ \mu^-$
/ LHCb collaboration
A search for the rare decay $D^0 \to \mu^+ \mu^-$is performed using a data sample, corresponding to an integrated luminosity of 0.9 fb$^{-1}$, of $pp$ collisions collected at a centre-of-mass energy of 7 TeV by the LHCb experiment. [...]

Study of $B^{0} \rightarrow D^{*-}\pi^{+}\pi^{-}\pi^{+}$ and $B^{0} \rightarrow D^{*-}K^{+}\pi^{-}\pi^{+}$ decays
/ LHCb Collaboration
Using proton-proton collision data collected by the LHCb experiment at $\sqrt{s} =$ 7 TeV, corresponding to an integrated luminosity of 1.0 fb$^{-1}$, the ratio of branching fractions of the $B^{0}\rightarrow D^{*-}\pi^{+}\pi^{-}\pi^{+}$ decay relative to the $B^{0} \rightarrow D^{*-}\pi^{+}$ decay is measured to be \begin{equation*} \frac{\mathcal{B}(B^{0}\rightarrow D^{*-}\pi^{+}\pi^{-}\pi^{+})}{\mathcal{B}(B^{0} \rightarrow D^{*-}\pi^{+})} = 2.64 \pm 0.04\,(\text{stat.}) \pm 0.13\,(\text{syst.})\, . \label{eq:CF_BF_ratio_result} \end{equation*} The Cabibbo-suppressed decay $B^{0}\rightarrow D^{*-}K^{+}\pi^{-}\pi^{+}$ is observed for the first time and the measured ratio of branching fractions is \begin{equation*} \frac{\mathcal{B}(B^{0}\rightarrow D^{*-}K^{+}\pi^{-}\pi^{+})}{\mathcal{B}(B^{0} \rightarrow D^{*-}\pi^{+}\pi^{-}\pi^{+})} = (6.47 \pm 0.37\,(\text{stat.}) \pm 0.35\,(\text{syst.})) \times 10^{-2} \label{eq:CS_BF_ratio_result}\, .

Measurement of the $B^0 \to K^{*0}e^+e^-$ branching fraction at low dilepton mass
/ LHCb Collaboration
The branching fraction of the rate decay $B^0 \rightarrow K^{*0}e^+e^-$ in the dilepton mass region from 30 to 1000 MeV$/c^2$ has been measured by the LHCb experiment, using $pp$ collision data, corresponding to an integrated luminosity of 1.0 fb$^{-1}$, at a centre-of-mass energy of 7 TeV. The decay mode $B^0 \rightarrow J/\psi(e^+e^-) K^{*0}$ is utilized as a normalization channel. [...]
