摘要

日本J-PARC的彗星实验旨在寻找铝核的介子到电子的转换，在90%的置信水平上实现了比目前上限高4个数量级的灵敏度。质子束流线最近已经完成，在实验的α阶段，μ子已经成功地通过弯曲的螺线管传输。在本文中，我们将介绍Phase-alpha光束测量的初步结果，中间灵敏度实验(COMET Phase-I)的现状，以及COMET Phase-II的最终目标。

A search for a muon to electron conversion in COMET

Abstract The COMET experiment at J-PARC, Japan, aims to search for muon to electron conversion with aluminium nuclei, achieving a sensitivity four orders of magnitude higher than the current upper limit at a 90% confidence level. The proton beam line has recently been completed, and muons have been successfully transported through the curved solenoid in the Phase-alpha of the experiment. In this paper, we will present preliminary results from the Phase-alpha beam measurement, the status of the intermediate sensitivity experiment (COMET Phase-I), and the ultimate goal of COMET Phase-II.
