Description
The NA62 experiment at the CERN SPS reports the first search for K+→ π+ ν ν¯ using the decay-in-flight technique, based on a sample of 1.21× 10 11 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+ ν ν¯ branching ratio at 95% CL.
