摘要

J-PARC的彗星实验旨在寻找μ−N→e−N中介子到电子转换的轻子味违反过程，其分支比灵敏度优于10−16，以探索超出标准模型的大多数良好激励理论模型预测的参数区域。对这种灵敏度的需求对光束线和探测器系统都提出了一些严格的要求。介绍了实验的研究现状和发展前景，并对实验进行了综述。

Project of Muon LFV at J-PARC

The COMET Experiment at J-PARC aims to search for a lepton-flavour violating process of muon to electron conversion in a muonic atom, $μ^{-} N \to e^{-} N$ , with a branching-ratio sensitivity of better than $10^{- 16}$ in order to explore the parameter region predicted by most of well-motivated theoretical models beyond the Standard Model. The need for this sensitivity places several stringent requirements on both the beam-line and detector systems. The current R&D status and prospects of experiment are presented in addition to the experimental overview.
