Measurement of the branching fraction ratio ${\cal B}(B_{c}^{+} \to \psi(2S)\pi^+)/{\cal B}(B_{c}^{+} \to J/\psi\pi^+)$
Using the $pp$ collision data collected by LHCb at center-of-mass energies $\sqrt{s} \, = 7 \, {\rm TeV} \,$ and $8 \, {\rm TeV} \,$, corresponding to an integrated luminosity of $3 \, \mathrm{fb}^{-1} \,$, the ratio of the branching fraction of the $B_{c}^{+} \to \psi(2S)\pi^+$ decay relative to...
