title = "Constraints on the KS0 →μ+μ- Branching Fraction",
abstract = "A search for the decay KS0→μ+μ- is performed using proton-proton collision data, corresponding to an integrated luminosity of 5.6 fb-1 and collected with the LHCb experiment during 2016, 2017, and 2018 at a center-of-mass energy of 13 TeV. The observed signal yield is consistent with zero, yielding an upper limit of B(KS0→μ+μ-)<2.2×10-10 at 90\% C.L.. The limit reduces to B(KS0→μ+μ-)<2.1×10-10 at 90\% C.L. once combined with the result from data taken in 2011 and 2012.",
