Recent results from MEG and status update for MEG II

MEG II Collaboration

Research output: Contribution to journalConference articlepeer-review

Abstract

The MEG experiment completed data taking in 2013 after several years and published in 2016 the most stringent upper limit on the BR(μ+ → e+γ) < 4.2 × 10−13 at 90 % confidence level. Recently, the search for μ+ → e+X, X → γγ was conducted using the full MEG data sample and the results reported. To improve the sensitivity to the BR(μ+ → e+γ) down to 6 × 10−14, the experiment has been upgraded as MEG II. The MEG II apparatus is ready for an engineering run at the end of 2021. Furthermore, MEG II plans to perform a measurement of the beryllium anomaly in the beginning of 2022.
