Search for K S ( L ) 0 → μ + μ − μ + μ − decays at LHCb

A search for K S ( L ) 0 → 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 fi...

Zusammenfassung:	A search for K S ( L ) 0 → 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 ( K S 0 → μ+μ-μ+μ- )
