Measurement of the Ratio of Branching Fractions $\cal{B}\mathrm{(B^{\pm} \rightarrow J/\psi \pi^{\pm})/\cal{B}\mathrm{(B^{\pm} \rightarrow J/\psi K^{\pm})}}$ at $\sqrt{\mathrm{s}}=7~\mathrm{TeV}$ with the LHCb Detector

The ratio of the branching fractions of the decays $\mathrm{B^{\pm} \rightarrow J/\psi \pi^{\pm}}$ and $\mathrm{B^{\pm} \rightarrow J/\psi K^{\pm}}$ has been measured with the LHCb detector in proton-proton collisions at a centre-of-mass energy of $\sqrt{\mathrm{s}}=7~\mathrm{TeV}$. The analysis is...
