The Mu3e experiment is a new search for the lepton-flavour violating decay of a positive muon into two positrons and one electron. See here for a an overview of the experiment.

Search for the forbidden decay $\mu^+ \to e^+ e^+ e^-$The Mu3e experiment is a new search for the lepton-flavour violating decay of a positive muon into two positrons and one electron.

Mu3e is a particle physics experiment at the Paul Scherrer Institute, searching for decays of anti - muons (Mu) to an electron and two positrons (3e). [1][2] This decay is extremely unlikely in the Standard Model of particle physics, as it changes the lepton number.

Oct 29, 2017 · The Mu3e Experiment searches for the lepton-flavour violating decay of a positive muon to two positrons and an electron. A detailled description of the experiment can be found on the homepage at the Paul Scherrer Institute (PSI).

Feb 21, 2019 · The Mu3e detector is based on thin monolithic active silicon pixel sensors for tracking in conjunction with scintillating fibers and tiles for timing measurements. The Mu3e apparatus is under constructions and first data is expected in 2020.

Jan 24, 2025 · The Mu3e experiment aims to probe the $\mu^+ \rightarrow e^+e^-e^+$ decay with a sensitivity of approximately $\mathcal{O}(10^{-15})$ in its Phase-1 and plans to achieve a sensitivity of $\mathcal{O}(10^{-16})$ after future upgrades.

The Mu3e experiment is designed to search for charged lepton flavour violation in the process μ+→e+e−e+ with a branching ratio sensitivity of 10−16 .

The Mu3e Collaboration aims to search for the LFV decay μ → e e e with a precision of one in 10 16 muon decays. The Mu3e experiment is currently being built at the Paul-Scherrer Institut (PSI). The invariant mass of μ → e e e signal decays equals the muon rest mass invariant mass m μ.

Sep 24, 2020 · The Mu3e experiment aims to find or exclude the lepton flavour violating decay μ → eee at branching fractions above 10−16. A first phase of the experiment using an existing beamline at the Paul Scherrer Institute (PSI) is designed to reach a …

The Mu3e experiment will search for the decay of a muon to three electrons, which is violating lepton flavor conservation. Since this decay is suppressed to unobservable levels in the standard model of particle physics, any measurement of this decay would be a clear sign of new physics.
