CERN experiment sees hints of a rare kaon decay

In a seminar on 27 March at CERN, the NA62 collaboration reported a candidate event of an ultra-rare charged kaon decay found using a new “in-flight decay” approach. While this single event cannot be used to probe beyond-Standard-Model physics, it demonstrates that the approach works well and can be applied to catch more events in the next run of data-taking, which kicks off in mid-April.
