Abstract

A search for K0S(L) → μ+ μ− μ+ μ− decays is performed using proton-proton collision data collected by the LHCb experiment at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 5.1 fb^−1. No evidence for signal is found. The 90% confidence level upper limits are the first set for both decays and are B(K0S → μ+ μ− μ+ μ−) < 5.1 × 10^−12 and B(K0L → μ+ μ− μ+ μ−) < 2.3 × 10^−9.
