在PADME上用多轻子事件寻找新物理

Searching for New Physics with multilepton events at PADME

Gabriele Martelli, Paolo Ciafaloni, Mauro Raggi

摘要:

PADME实验正在寻找$e^{+}e^{-} \to γA'$过程中的暗光子$A'$,假设$A'$衰变为不可见的粒子。在扩展的暗区模型中,在$e^{+}e^{-} \to h' A'$的过程中,一个暗希格斯粒子$h'$可以和$A'$一起产生。如果$h'$质量大于$A'$质量的两倍,则最终状态将由三个$e^{+}e^{-}$对组成。这种极其罕见的过程可以通过PADME实验进行探索,该实验可以获得第一个测量结果,并对标准模型之外的物理模型施加限制。

英文摘要:

The PADME experiment is searching for the Dark Photon $A'$ in the $e^{+}e^{-} \to γA'$ process, assuming a $A'$ decay into invisible particles. In extended Dark Sector models, a Dark Higgs $h'$ can be produced alongside $A'$ in the process $e^{+}e^{-} \to h' A'$. If the $h'$ mass is greater than twice the $A'$ mass the final state will be composed by three $e^{+}e^{-}$ pairs. Such extremely rare process is explorable by the PADME experiment, which could get a first measure and impose limits on models of physics beyond the Standard Model.
