LHCb: Search for the rare decays $B^0_s \to \mu^+\mu^-\mu^+\mu^-$ and $B^0 \to \mu^+\mu^-\mu^+\mu^-$ at LHCb
A search for the decays $B^0_s \to \mu^+\mu^-\mu^+\mu^-$ and $B^0 \to \mu^+\mu^-\mu^+\mu^-$ in a data sample of 1.0 inverse femtobarns collected with the LHCb detector in 2011 is discussed. In the SM, the non-resonant $B^0_s \to \mu^+\mu^-\mu^+\mu^-$ branching fraction is expected to be < 10$^{-...
