Overview

abstract

• The NA62 experiment at the CERN SPS reports the first search for K →π νν¯ using the decay-in-flight technique, based on a sample of 1.21×1011 K decays collected in 2016. The single event sensitivity is 3.15×10−10, corresponding to 0.267 Standard Model events. One signal candidate is observed while the expected background is 0.152 events. This leads to an upper limit of 14×10−10 on the K →π νν¯ branching ratio at 95%25 CL. © 2019 The Author

The single event sensitivity is 3.15×10−10, corresponding to 0.267 Standard Model events. One signal candidate is observed while the expected background is 0.152 events.
