Abstract

The Mu2e experiment aims to improve, by four orders of magnitude, current sensitivity in the search for the charged-lepton flavor violating (cLFV) neutrino-less conversion of a negative muon into an electron. The conversion process will be identified by a distinctive signature of a mono-energetic electron with energy slightly below the muon rest mass. In the Standard Model this process has a negligible rate. However, in many Beyond the Standard Model scenarios its rate is within the reach of Mu2e sensitivity. In this paper, we explain the Mu2e design guidelines and summarize the status of the experiment.

Highlights

  • Since flavor violation has been established in quarks and neutrinos, it is natural to expect flavor violating processes among the charged leptons

  • Albeit in the Standard Model (SM) there is not any global symmetry requiring lepton flavor violation, when massive neutrinos are introduced, the SM provides a mechanism for charged-lepton flavor violating (cLFV) via neutrino-mixing in loops

  • The cLFV muon searches are of particular interest because of the possibility to carry out clean measurements free of theoretical background and the availability of high intensity muon beams

Summary

Introduction

Since flavor violation has been established in quarks and neutrinos, it is natural to expect flavor violating processes among the charged leptons. A solid international program continues nowadays with the upgrade of MEG [7, 8], the proposed Mu3e search at PSI [7, 9] as well as the searches for muon to electron conversion with Mu2e at Fermilab [10] and COMET at JPARC [7, 11]. These experiments plan to extend the current sensitivity of one or more orders of magnitude providing access to new physics mass scales in the 103 -104 GeV range, well beyond what can be directly probed at colliders. This has been exploited in summer 2018 by submitting a joint cLFV report, across experiments, to the European Strategy group [13]
