Observation of the $B_s^0 \rightarrow J/\psi \phi \phi$ decay
Observation of the $B_s^0 \rightarrow J/\psi \phi \phi$ decay
The $B_s^0 \rightarrow J/\psi \phi \phi$ decay is observed in $pp$ collision data corresponding to an integrated luminosity of 3 fb$^{-1}$ recorded by the LHCb detector at centre-of-mass energies of 7 TeV and 8 TeV. This is the first observation of this decay channel, with a statistical significance of 15 …
