The differential branching fraction of the decay $\Lambda_b^0\rightarrow\Lambda\mu^+\mu^-$ is measured as a function of the square of the dimuon invariant mass, $q^2$. A yield of $78\pm12$ $\Lambda_b^ ...

The B0s→J/ψK0S branching fraction is measured in a data sample corresponding to 0.41 fb−1 of integrated luminosity collected with the LHCb detector at the LHC. This channel is sensitive tothe penguin ...

A search for the rare decays B0s→μ+μ− and B0→μ+μ− is performed with data collected in 2011 and 2012 with the LHCb experiment at the Large Hadron Collider. The data samples comprise 1.1  fb−1 of proton-proton ...
