Properties of the orbitally excited (L=1) $B_s$ states are studied using 1.0 fb$^{-1}$ of pp collisions at $\sqrt{s} =7$ TeV collected with the LHCb detector. The first observation of the $B_{s2}^*(5840)^0$ meson decaying to $B^{*+} K^-$ is reported, and the corresponding branching fraction measured relative to the $B^+ K^-$ decay mode. [...]

Measurement of the $C\!P$ asymmetry in $B^0 \to K^{*0} \mu^+ \mu^-$ decays / LHCb Collaboration
A measurement of the $C\!P$ asymmetry in $B^0 \rightarrow K^{*0} \mu^+ \mu^-$ decays is presented, based on 1.0$\mbox{\,fb}^{-1}$ of $pp$ collision data recorded by the LHCb experiment during 2011.

First observation of the decays $\bar{B}^0_{(s)}\to D_s^+K^-\pi^+\pi^-$ and $\bar{B}^0_s\to D_{s1}(2536)^+\pi^-$ / LHCb collaboration

The branching fractions, normalized with respect to $\bar{B}^0_{s}\to D_s^+\pi^-\pi^+\pi^-$ and $\bar{B}^0_{s}\to D_s^+K^-\pi^+\pi^-$, respectively, are measured to be $\frac{B(\bar{B}^0_{s}\to D_s^+K^-\pi^+\pi^-)}{B(\bar{B}^0_{s}\to D_s^+\pi^-\pi^+\pi^-)} = (5.2\pm0.5\pm0.3)\times10^{-2}$, $\frac{B(\bar{B}^0\to D_s^+K^-\pi^+\pi^-)}{B(\bar{B}^0_{s}\to D_s^+K^-\pi^+\pi^-)} = 0.54\pm0.07\pm0.07$, where the first uncertainty is statistical and the second is systematic.

The $B^0$--$\bar B^0$ oscillation frequency $\Delta m_d$ is measured by the LHCb experiment using a dataset corresponding to an integrated luminosity of $1.0\,$fb$^{-1}$ of proton-proton collisions at $\sqrt{s} = 7\,$TeV, and is found to be $\Delta m_d = 0.5156 \pm 0.0051\,($stat.$) \pm 0.0033\,($syst.$)\,$ps$^{-1}$. The measurement is based on results from analyses of the decays $B^0 \to D^- \pi^+$ ($D^- \to K^+ \pi^- \pi^-$) and $B^0 \to J\ \psi K^{*0}$ ($J\ \psi \to \mu^+ \mu^-$, $K^{*0} \to K^+ \pi^-$) and their charge conjugated modes..

Measurement of the time-dependent $CP$ asymmetry in $B^0 \to J/\psi K^0_{\rm S}$ decays / LHCb Collaboration
This Letter reports a measurement of the $CP$ violation observables $S_{J/\psi K^0_{\rm S}}$ and $C_{J/\psi K^0_{\rm S}}$ in the decay channel $B^0 \rightarrow J/\psi K^0_{\rm S}$ performed with 1.0 fb$^{-1}$ of $pp$ collisions at $\sqrt{s}=7$ TeV collected by the LHCb experiment.

Measurements of $B_c^+$ production and mass with the $B_c^+ \to J/\psi \pi^+$ decay / LHCb Collaboration
Measurements of $B_c^+$ production and mass are performed with the decay mode $B_c^+ \to J/\psi \pi^+$ using 0.37 fb$^{-1}$ of data collected in $pp$ collisions at $\sqrt{s}=7$~TeV by the LHCb experiment.
