Observation of the B s 0 → J/ψϕϕ decay
© 2016, The Author(s). The Bs0 → J/ψϕϕ 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 st...

description | © 2016, The Author(s). The Bs0 → J/ψϕϕ 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 standard deviations. The mass of the Bs0 meson is measured to be 5367.08 ± 0.38 ± 0.15 MeV/c2. The branching fraction ratio ℬ(Bs0 → J/ψϕϕ)/ℬ(Bs0 → J/ψϕ) is measured to be 0.0115 ± 0.0012− 0.0009+ 0.0005. In both cases, the first uncertainty is statistical and the second is systematic. No evidence for non-resonant Bs0 → J/ψϕK+K− or Bs0 → J/ψK+K−K+K− decays is found. |
