Abstract

A Monte Carlo study of possible background processes in a search for τ→μγ decay has been performed for conditions of the Super c−τ factory (SCTF) at a center-of-mass energy 3.686 GeV, 3.77 GeV and 4.17 GeV. The background from τ+τ− events has been analysed. Selection criteria for background suppression are suggested and necessary requirements on the detector characteristics have been found. A possible upper limit for Bτ→μγ at SCTF is about (1.5÷2.5)×10−10. The SCTF can successfully compete with the Super B-factory in a search for τ→μγ decay.
