Abstract

We have observed the decay K_L→μ⁺μ^-γγ at the KTeV experiment at Fermilab. This decay presents a formidable background to the search for new physics in K_L→π⁰μ⁺μ^-. The 1997 data yielded a sample of 4 signal events, with an expected background of 0.155±0.081 events. The branching ratio is script B sign (K_L →μ⁺μ^-γγ)=[10.4^-5.9 ^+7.5(stat)±0.7(syst)]×10^-9 with m_γγ≥1 MeV/c², consistent with a QED calculation which predicts (9.1±0.8)×10^-9.
