在这项工作中，我们探索了新的自旋1态的轴向耦合的标准模型费米子。我们发展了一种基于τ衰变数据和SU（3）味对称性的数据驱动方法来估计它们的强子衰变率。我们推导出几个基准模型的当前和未来的实验约束。我们的框架是通用的，可用于任意矢量和轴向耦合到夸克的模型。我们已经通过将它们合并到D方舟Cast包中公开了我们的计算，请参阅https：//gitlab。com/darkcast/releases.
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) 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 D ark C ast package, see https://gitlab. com/darkcast/releases.
