MEG II的轻子味破坏轴子

Lepton-flavor violating axions at MEG II

Yongsoo Jho, Simon Knapen, Diego Redigolo

摘要:

我们研究了现有MEG数据对通过$μ^+ \to e^+ a γ$产生的违反轻子味的类轴子粒子的敏感性,并估计了即将到来的MEG II实验在这个通道中的发现潜力。如果可以在专用运行中以降低的射束强度实施新的触发,则可以显著提高MEG II信号效率。这项研究将建立世界领先的测量在这个渠道只有1个月的数据。

英文摘要:

We study the sensitivity of the existing MEG data to lepton flavor violating axion-like particles produced through $μ^+ \to e^+ a γ$ and estimate the discovery potential for the upcoming MEG II experiment in this channel. The MEG II signal efficiency can be improved significantly if a new trigger can be implemented in a dedicated run with a reduced beam intensity. This search would establish the world leading measurement in this channel with only 1 month of data taking.
