标题： The Quest for $μ\to e γ$ and its Experimental Limiting Factors at Future High Intensity Muon Beams

摘要： 寻找轻子味违反衰变 $\mu \to e \gamma$ 的研究利用了目前最强烈的连续μ子束，这些束每秒可以输送 $\sim 10^8$ 个μ子。 在接下来的十年中，各种设施的加速器升级预计会实现，使得拥有每秒 $10^9$ 甚至 $10^{10}$ 个μ子强度的连续束成为可能。 我们研究将定义搜索 $\mu \to e \gamma$ 的最终性能及灵敏度的实验限制因素，在这些极高速率的连续束下。 然后我们考虑一些概念性的探测器设计，并评估相应的灵敏度作为束流强度的函数。 显示英文摘要

摘要： The search for the Lepton Flavor Violating decay $\mu \to e \gamma$ exploits the most intense continuous muon beams, which can currently deliver $\sim 10^8$ muons per second. In the next decade, accelerator upgrades are expected in various facilities, making it feasible to have continuous beams with an intensity of $10^9$ or even $10^{10}$ muons per second. We investigate the experimental limiting factors that will define the ultimate performances, and hence the sensitivity, in the search for $\mu \to e \gamma$ with a continuous beam at these extremely high rates. We then consider some conceptual detector designs and evaluate the corresponding sensitivity as a function of the beam intensity.
