Introduction to the Measurement

The Mu2e Experiment will measure the rate of muons that convert directly into electrons in the field of a nucleus without the accompanying neutrinos that the standard model of particle physics predicts. This process is all but forbidden in the standard model due to the apparent conservation of a property known as “flavor”. Muons have one flavor and electrons another. This means if flavor is conserved, a muon cannot decay to electrons without carrying forward the muon flavor in the interaction with the production of a muon neutrino. Likewise, an electron cannot appear in the decay without the cancellation of this new flavor with an anti-electron neutrino. Mu2e relies on momentum and energy conservation to determine whether the muon decay proceeded in a way that conserves flavor, or violates flavor conservation.
