First observation of the decay $K_{S} \to \pi^{0}\mu^{+}\mu^{-}$ at the NA48 experiment at CERN
A search for the $K_{S} \to \pi^{0}\mu^{+}\mu^{-}$ decay was performed by the NA48/1 Collaboration at the CERN SPS accelerator. Six events were found with a background expectation of $0.22^{+0.18}_{-0.11}$ in the data collected in 2002 from the high-intensity $K_{S}$ run. The measured branching rati...
