Searches for rare $$ {B}_s^0 $$ and B0 decays into four muons

Journal of High Energy Physics, vol. 2022

Abstract

Abstract Searches for rare $$ {B}_s^0 $$ B s 0 and B0 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.
