Rare B-s(0) and B-0 decays into four muons were searched for using proton-proton collision data recorded by the LHCb experiment. No evidence for the searched decays was found, and upper limits on their branching fractions were set.
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/psi 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 x 10(-10) and 2.6 x 10(-9) are set.
