论文摘要
标准模型的Abelian U（1）量规组扩展代表了解决一些最紧迫的粒子物理问题的最小方法之一，并在各种实验搜索中提供了丰富的现象学。在这项工作中，我们专注于MEV-TO-GEV质量范围内的Bararophilic Vector介体模型，尤其是目前，量规矢量场首次衰减几乎是任意的HADRONIC最终状态。仅使用很少的理论近似值，我们严格遵循计算中的媒介中的优势理论。我们研究了对不同模型中光矢量颗粒的质量和耦合（for）在（未来）实验限制（触及）对总（未来）实验限制（触及）的影响。我们将结果与文献中的当前结果进行了比较。我们的计算在Python软件包中公开可用，以计算各种矢量粒子衰减量，以描述Leptonic和Hadronic衰减特征，以进行实验搜索。
Abelian U(1) gauge group extensions of the Standard Model represent one of the most minimal approaches to solve some of the most urgent particle physics questions and provide a rich phenomenology in various experimental searches. In this work, we focus on baryophilic vector mediator models in the MeV-to-GeV mass range and, in particular, present, for the first time, gauge vector field decays into almost arbitrary hadronic final states. Using only very little theoretical approximations, we rigorously follow the vector meson dominance theory in our calculations. We study the effect on the total and partial decay widths, the branching ratios, and not least on the present (future) experimental limits (reach) on (for) the mass and couplings of light vector particles in different models. We compare our results to current results in the literature. Our calculations are publicly available in a python package to compute various vector particle decay quantities in order to describe leptonic as well as hadronic decay signatures for experimental searches.
