Abstract

We present the angular distribution of the four-fold

and

decays in the Standard Model and family non-universal

model. At the quark level, these decays are governed by the

transition. Along with different angular observables, we provide predictions of differential branching ratios, forward-backward asymmetry, and longitudinal polarization fractions of

and

mesons. Our analysis shows that the signatures of the family non-universal

model are more distinct in the observables associated with the

decay than in those associated with the

decay. Future measurements of the predicted angular observables, both at current and future high energy colliders, will provide useful complementary data required to clarify the structure of the family non-universal

model in

processes.

族非通用 Z ′模型对衰变角观测值的影响* * 由巴基斯坦高等教育委员会通过（NRPU/20-15142）提供支持

我们介绍了标准模型和族非普适性模型中的四折和衰变的角分布。在夸克层面，这些衰变受过渡的支配。除了不同的角度观测指标，我们还提供了和介子的差分支比、前后不对称和纵向极化分数的预测。我们的分析表明，在与衰变相关的观测指标中，族非普适模型的特征比在与衰变相关的观测指标中更为明显。未来在当前和未来的高能对撞机上对所预测的角度观测数据进行测量，将为澄清=过程中的族非普适模型结构提供有用的补充数据。
