Abstract:
The MEG experiment has set the latest limit of 5.7 x10^-13
(90 % C.L.) on the branching ratio of the
charged lepton
flavor violating decay
μ->eγ, making use of the most intense continuous surface
muon beam in the world at the Paul Scherrer Institut (PSI), Villigen, Switzerland. High resolutions in
terms of energy, timing and relative opening angle are needed in the detection of the
e^+and gamma,
requiring careful calibration and monitoring of the experimental apparatus. A dedicated calibration
method involving Mott scattering of a monochromatic positron beam at energies close to the MEG signal
energy is presented
