Search for K%2b → π%2bνν: First NA62 Results Conference Paper uri icon

abstract

  • NA62 has searched for the K%2b → π%2bνν 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 × 1011 decays. Assuming that the event is background, an upper limit of 1.4 × 10−9 (95%25 CL) has been placed. Prospects for further improvements of the measurement are given. © Springer Nature Switzerland AG 2019.
