The Mu2e experiment at Fermilab: a status report in view of the first data taking phase — •Anna Ferrari, Stefan E. Mueller, Oliver Knodel, and Reuven Rachamin for the Mu2e collaboration — Helmholtz- Zentrum Dresden-Rossendorf, Dresden, Germany

The Mu2e experiment, which is currently entering the final installation phase at the Fermi National Accelerator Laboratory in USA, will search for the charged-lepton flavor violating neutrino-less conversion of negative muons into electrons in the field of an aluminum nucleus. A conversion signal would require physics beyond the Standard Model, and the aim of Mu2e is to reach a single-event sensitivity four order of magnitude better than previous experiments. This can be achieved through an efficient production and transport of the muon beam, a rigorous control of all backgrounds that could mimic the monoenergetic conversion electrons, and an accurate normalization of the signal events. The present status of the Mu2e experiment will be presented, while the main detector subsystems has been installed at their final locations inside the Mu2e hall, and the strategies of the first data taking period have been defined.
