A measurement of the $K^+ \to \pi^+ \mu^+ \mu^-$ decay

A sample of $2.8 \times 10^4$ $K^+ \to \pi^+ \mu^+ \mu^-$ candidates with negligible background was collected by the NA62 experiment at the CERN SPS in 2017-2018. The model-independent branching fraction is measured to be $(9.15 \pm 0.08) \times 10^{-8}$, a factor three more precise than previous m...
