摘要

The MEG II experiment, based at the Paul Scherrer Institut in Switzerland, reports the result of a search for the decay ^+ →e^+ from data taken in the first physics run in 2021. No excess of events over the expected background is observed, yielding an upper limit on the branching ratio of ℬ ( ^+ →e^+ ) < 7.5 × 10^-13 (90 ℬ ( ^+ →e^+ ) < 3.1 × 10^-13 (90
