在超级$c -τ$工厂搜索$τ\toμ+γ$衰变

Search for $τ\toμ+γ$ decay at Super $c -τ$ factory

A. V. Bobrov, A. E. Bondar

摘要:

在超级$c-τ$工厂(CTF)的条件下(在质心能量为3.686 GeV,3.77 GeV和4.17 GeV),在搜索$τ\to μγ$衰变的可能的背景过程的蒙特卡罗研究已被执行。分析了$τ^{+}τ^{-}$事件的背景。提出了背景抑制的选择准则,并找到了对探测器特性的必要要求,CTF可以成功地与超级B工厂竞争探测$τ\to μγ$衰变。

英文摘要:

A Monte Carlo study of possible background processes in a search for $τ\to μγ$ decay has been performed for conditions of the Super $c-τ$ factory (CTF) (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. The CTF can successfully compete with the Super B-factory in a search for $τ\to μγ$ decay.
