Searches for rare $ {B}_s^0 $ and B$^{0}$ decays into four muons

Searches for rare $ {B}_s^0 $ and B$^{0}$ decays into four muons are performed using proton-proton collision data recorded by the LHCb experiment, corresponding to an integrated luminosity of 9 fb$^{−1}$. Direct decays and decays via light scalar and J/ψ resonances are considered. No evidence for th...

Zusammenfassung:Searches for rare $ {B}_s^0 $ and B$^{0}$ decays into four muons are performed using proton-proton collision data recorded by the LHCb experiment, corresponding to an integrated luminosity of 9 fb$^{−1}$. Direct decays and decays via light scalar and J/ψ resonances are considered. No evidence for the six decays searched for is found and upper limits at the 95% confidence level on their branching fractions ranging between 1.8 × 10$^{−10}$ and 2.6 × 10$^{−9}$ are set.[graphic not available: see fulltext]
