ABSTRACT

In the Standard Model (SM) of electroweak interactions the Lepton Flavour Violating (LFV) processes are forbidden at all; however almost all SM extensions predict processes which do not conserve the lepton number. In particular the supersymmetric models predict branching ratios for LFV reactions at level of 10−(13÷16), which should be experimentally observable. The µ → eγ process is one of the golden channels for the LFV observation [1, 6]. The present limit for the branching ratio (µ → eγ)/(µ → ALL) is 1.2 × 10−11 [6] and the aim of the MEG experiment at Paul Scherrer Institute (PSI) is to improve this limit by a factor ∼ 100. This challenging goal requires refined and innovative detection techniques in order to reach very high resolutions in the measurement of γ and e+ energy, momentum and timing. One of the key elements is the Liquid Xenon (LXe) e.m. calorimeter, the main subject of this paper. More... »
