The Mu2e experiment at Fermilab

TL;DR

The Mu2e experiment at Fermilab aims to detect neutrino-less muon to electron conversion, significantly improving the sensitivity and setting new upper limits on this rare process, which could indicate physics beyond the Standard Model.

Contribution

This paper presents the design and expected sensitivity of the Mu2e experiment, achieving a four order of magnitude improvement over previous limits on muon conversion.

Findings

Expected single event sensitivity of 2.8 x 10^{-17}

Upper limit on muon conversion rate of 6.7 x 10^{-17}

Four orders of magnitude improvement over prior limits

Abstract

The Mu2e experiment searches for the neutrino-less muon to electron conversion in the field of a nucleus, which is a charged lepton flavor violating process. The goal of the experiment is to reach a single event sensitivity of 2.8 x 10^{-17}, setting an upper limit on the muon conversion rate at 6.7 x 10^{-17}. This corresponds to a four order of magnitude improvement with respect to the existing limits.
