Lepton Flavour Violating Muon Decay at MEG

TL;DR

The MEG experiment aims to detect the rare lepton flavor violating decay of muons into electrons and gamma rays, testing physics beyond the Standard Model with high sensitivity.

Contribution

This paper presents the experimental setup, construction progress, and prospects for the 2008 physics run of the MEG experiment searching for $oldsymbol{ ext{μ}^+ o ext{e}^+ ext{γ}}$ decay.

Findings

Detector construction completed in 2007

First physics run planned for 2008

Sensitivity to branching ratio of 10^{-13}

Abstract

The MEG Experiment searches for a lepton flavour violating decay, $\mu^+\to\mathrm{e}^+\gamma $, with a branching-ratio sensitivity of $10^{-13}$ in order to explore the parameter region predicted by many theoretical models beyond the Standard Model. Detector construction and the Engineering Run were completed in 2007, and the first Physics Run will be carried out in 2008. In this paper, the prospects of MEG Physics Run in 2008 is described in addition to the experimental overview.
