论文摘要
最近，Altmannshofer，Dror和Gori（2022）声称有四点互动，$ W $ - $ - $ \ ell $ - $ - $ - $ - $ - $ν$ - $ a $，在x轴类粒子（Alp）的静电歧视场景中，在搜索$ pm pm pm pm pm pm pm pm pm pm pm pm pm pm pm pm pm pm pm pm pm pm pm pm pm pm pm pm pm pm pm pm pm pm pm pm pm pm pm pm pm pm pm pm pm pm pm pm pm pm pm pm pm fe以及$ W $玻色子的衰变，由于新颖的能量增强。受这个有趣的发现的启发，我们首先提出了新的T通道过程，$ e^{+} e^{ - } \rightArrowν_ea \ bar {ν_e} $和$ e^{ - } p \rightArrowν_ea J $ a J $，用于电动alps $ $ $ $ $ $ - 当碰撞能量增加时，相互作用并具有明显的能量增强行为。另一方面，较重的$ e $ alps主要是衰减为手性异常引起的光子对，而不是电子 - 峰值对。因此，对这些T光子对的T通道过程的研究以及$ E^+ E^ - $和$ EP $ colliders的缺失能量打开了新的大门，在高能量coll派中搜索$ E $ alps。提出的搜索策略不仅旨在产生更大的阿尔卑斯山的生产率，而且还试图区分电动竞争的Alp-Lepton相互作用与具有电动的耐电相互作用。
Recently, Altmannshofer, Dror and Gori (2022) claimed there is a four-point interaction, $W$-$\ell$-$ν$-$a$, in the electroweak-violating scenario of axion-like particle (ALP) and lepton interactions which plays a critical role in searching for ALPs from $π^{\pm}$, $K^{\pm}$ mesons and $W$ boson decays because of the novel energy enhancements. Inspired by this interesting finding, we first propose new t-channel processes, $e^{+}e^{-}\rightarrowν_e a\bar{ν_e}$ and $e^{-}p\rightarrowν_e a j$, for electrophilic ALPs ($e$ALPs) which also involve $W$-$\ell$-$ν$-$a$ four-point interaction and have obvious energy enhancement behaviors in their cross sections when the collision energy is increasing. On the other hand, heavier $e$ALPs mainly decay to a photon pair induced by the chiral anomaly instead of an electron-positron pair. Therefore, studies of these t-channel processes with a photon pair plus missing energy at $e^+ e^-$ and $ep$ colliders open a new door to search for $e$ALPs at high energy colliders. The proposed search strategies are not only aiming to generate a larger production rate of ALPs, but also trying to distinguish electroweak-violating ALP-lepton interactions from electroweak-preserving ones.
