Precise measurement of the Decay $K^\pm \to \pi^0\pi^0\mu^\pm\nu$

We report the first observation of the decay $K^{\pm} \rightarrow \pi^{0} \pi^{0} \mu^{\pm} \nu$ ($K^{00}_{\mu4}$) by the NA48/2 experiment at the CERN SPS. From 2437 detected signal candidates with a S/B ratio of about 6, the branching ratio of the decay is determined with high precision. In the...
