论文摘要
在这项工作中，我们探索了与标准模型费米子具有轴向耦合的新的Spin-1状态。我们开发了一种数据驱动的方法，以根据$τ$衰减的数据并使用su（3）$ _ {\ rm avely} $对称性来估算其耐腐烂率。我们为多种基准模型提供了当前和未来的实验约束。我们的框架是通用的，可用于与夸克的任意矢量和轴向耦合的模型。我们已通过将它们纳入黑暗播放包中，请参阅https://gitlab.com/darkcast/Releases，公开获得计算。
In this work, we explore new spin-1 states with axial couplings to the standard model fermions. We develop a data-driven method to estimate their hadronic decay rates based on data from $τ$ decays and using SU(3)$_{\rm flavor}$ symmetry. We derive the current and future experimental constraints for several benchmark models. Our framework is generic and can be used for models with arbitrary vectorial and axial couplings to quarks. We have made our calculations publicly available by incorporating them into the DarkCast package, see https://gitlab.com/darkcast/releases.
