Abstract

A search for K⁰_S(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(K⁰_S→ μ⁺μ⁻μ⁺μ⁻) < 5.1×10⁻¹² and B(K⁰_L→ μ⁺μ⁻μ⁺μ⁻) < 2.3×10⁻⁹.
