We present a measurement of the ratio of the ${\overline{B}}_{s}^{0}$ meson lifetime, in the flavor-specific decay to ${D}_{s}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$, to that of the ${\overline{B}}^{0}$ meson. The $pp$ collision data used correspond to an integrated luminosity of $1\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$, collected with the LHCb …

A search for the decay ${B}_{s}^{0}\ensuremath{\rightarrow}{D}^{*\ensuremath{\mp}}{\ensuremath{\pi}}^{\ifmmode\pm\else\textpm\fi{}}$ is presented using a data sample corresponding to an integrated luminosity of $1.0\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of $pp$ collisions collected by LHCb. This decay is expected to be mediated by a $W$-exchange diagram, with little contribution from …

A search for ${B}_{s}^{0}\ensuremath{\rightarrow}{\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}$ and ${B}^{0}\ensuremath{\rightarrow}{\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}$ decays is performed using $1.0\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of $pp$ collision data collected at $\sqrt{s}=7\text{ }\text{ }\mathrm{TeV}$ with the LHCb experiment at the Large Hadron Collider. For both decays, the number of observed events is consistent with …

The angular distributions and the partial branching fraction of the decay ${B}^{0}\ensuremath{\rightarrow}{K}^{*0}{\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}$ are studied by using an integrated luminosity of $0.37\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of data collected with the LHCb detector. The forward-backward asymmetry of the muons, ${A}_{\mathrm{FB}}$, the fraction of longitudinal polarization, …

The B s 0 – B ¯ s 0 oscillation frequency Δ m s is measured with 36 pb −1 of data collected in pp collisions at s = 7 TeV by the LHCb experiment at the Large Hadron Collider. A total …
