# The Mu2e experiment at Fermilab: a search for lepton flavor violation

## TL;DR

The Mu2e experiment at Fermilab aims to detect rare muon-to-electron conversion events, testing lepton flavor violation with unprecedented sensitivity using a specialized detector and a high-intensity muon beam.

## Contribution

This paper presents the design, expected performance, and physics goals of the Mu2e experiment, a novel search for charged lepton flavor violation.

## Key findings

- Projected sensitivity of 2.5×10⁻¹⁷ for muon-to-electron conversion
- Design of the experimental apparatus and detector performance expectations
- Estimated muon stopping in aluminum target over three years

## Abstract

The Mu2e experiment at Fermilab will search for the charged lepton flavor violating process of neutrino-less $\mu \to e$ coherent conversion in the field of an aluminum nucleus. About $7 \cdot 10^{17}$ muons, provided by a dedicated muon beam line in construction at Fermilab, will be stopped in 3 years in the aluminum target. The corresponding single event sensitivity will be $2.5\cdot 10^{-17}$. In this paper a brief overview of the physics explored by the $\mu \to e$ conversion is given, followed by a description of the Mu2e experimental apparatus and the expected detector performance.
