Measurement of the ratio of branching fractions for $B ^0_s \rightarrow \phi\mu\mu$ and $B ^0_s \rightarrow J/\psi \phi$
A measurement of the ratio of the branching fractions for $B ^0_s \rightarrow \phi\mu\mu$ and $B ^0_s \rightarrow J /\psi \phi$ as a function of the dimuon invariant mass with $1\rm{fb}^{-1}$ of data collected by the LHCb detector at $\sqrt{s}=7 \,\rm{TeV}$ during the 2011 run is reported. The rati...
