论文摘要
我们通过衰减$ z \ rightarrow a f \ bar {f} $在未来的$ z $工厂中检测到类似轴突的粒子(阿尔卑斯山(Alps)(Alps,称为“ A”)的前景。考虑到衰减通道$ a \rightArrowμ^+μ^ - $和$ a \ rightArrow b \ bar {b} $,四种类型的信号$μ^+μ^ - /e $,$ b /e $,$ b b /e $,$ e^+ e^+ e^+ e^+ e^ - μ^+μ^+μ^ - $ e^+ e^+ e^+ e^+ e^ - b b $ expored。我们证明,这些频道有望在$ z $工厂检测阿尔卑斯山,并在耦合上获得敏感性界限$ g_ {azz} $和$ g_ {aγZ} $。
We investigate the prospects for detecting axion-like particles (ALPs, dubbed as "a") via the decay $Z\rightarrow a f\bar{f}$ at future $Z$ factories. Considering the decay channels $a\rightarrow μ^+ μ^-$ and $a\rightarrow b \bar{b}$ , four types of signals $μ^+ μ^- /E$, $b b /E$, $e^+ e^- μ^+ μ^-$ and $e^+ e^- b b$ are explored. We demonstrate that these channels are promising for detecting ALPs at $Z$ factories and obtain the sensitivity bounds on the couplings $g_{aZZ}$ and $g_{aγZ}$.
