Search for $K^+\rightarrow \pi ^+\nu \overline{\nu }$: First NA62 Results

NA62 has searched for the $K^+\rightarrow \pi ^+\nu \overline{\nu }$ decay using a new kaon decay in-flight technique. One candidate event, compatible with the Standard Model prediction, has been observed from a sample of $1.2\times 10^{11}$ decays. Assuming that the event is background, an upper li...

description NA62 has searched for the $K^+\rightarrow \pi ^+\nu \overline{\nu }$ decay using a new kaon decay in-flight technique. One candidate event, compatible with the Standard Model prediction, has been observed from a sample of $1.2\times 10^{11}$ decays. Assuming that the event is background, an upper limit of $1.4\times 10^{-9}$ (95% CL) has been placed. Prospects for further improvements of the measurement are given.
