Search for decays of neutral beauty mesons into four muons

LHCb collaboration, R. Aaij, B. Adeva +768

A search for the non-resonant decays $B_s^0\to {\mu }^{+}{\mu }^{-}{\mu }^{+}{\mu }^{-}$ and $B^0\to {\mu }^{+}{\mu }^{-}{\mu }^{+}{\mu }^{-}$ is presented. The measurement is performed using the full R…
