New measurement of the $K^+ \to \pi^+\mu^+\mu^-$ decay
The flavor-changing neutral current decay K+ → π+μ+μ− (Kπμμ) is well suited to explore the Standard Model structure. A new measurement of this decay branching fraction and form factor has been performed by the NA62 experiment at CERN based on data collected in 2017–2018. From the selected sample of...
