Search for the lepton-flavour violating 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. See here for a an overview of the experiment.
Current news
New staging area for Mu3e
We have moved to a new staging area with a flow tent where we can assemble and prepare the experiment before inserting it into the magnet.
Mu3e Collaboration Meeting at PSI
The Mu3e collaboration met for two days at PSI to discuss detector construction and comissioning as well as the results of the 2025 run.
Outer Pixel Ladders
The Mu3e team in Oxford has produced first functional outer pixel ladders, a big step towards completing our detector.
