Description
The goal of the Mu2e experiment is to improve on the existing limit for the neutrinoless conversion of the muon to a monoenergetic electron by four orders of magnitude. This reaction is an example of a Charged Lepton Flavor Violation, so far not observed in any reactions. The existence of neutrino oscillation leads to a Standard Model prediction of the rate of the muon to electron that is far smaller than foreseeable experimental limits, consequently observation of the mu-e conversion is a clean indication of new physics. Moreover some models of new physics outside of the Standard Model predict a signal just beyond current limits. The proposed measurement will either see a signal or place dramatic limits on the flavor conservation properties of new physics models.
In this seminar I will give a brief account of the theoretical motivation than I would describe the experimental setup that is being developed at Fermilab. The experiment will utilize pulsed negative muon beam that is stopped in an aluminum target. Each stopped muon forms a muonic atom. The goal is to measure the rate of conversion of a muon into an electron relative to the rate of ordinary nuclear capture, with a single event sensitivity of 6e-17. A new low energy, high flux muon beam line using solenoids is being designed. The planned methods of detection of the conversion electron and of background suppression will be also covered by the seminar.
