In-flight search for K → π νν: First NA62 results Conference Paper uri icon

abstract

  • NA62 has searched for the K → π νν 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. © Copyright owned by the author(s) under the terms of the Creative Commons.
