研究了在一个提议的dz0工厂中探测左右对称模型（LRM）对过程+e−→µ+µ−的影响的潜力。在不同的正电子极化碰撞模式下，我们计算并比较了LRM框架内的各种观测值与标准模型（SM）预测的偏差，如总横截面、µ−的横向动量分布和µ−的前后电荷不对称性。此外，我们给出了可观测值与LRM参数之间的关系。我们得出结论，通过在az0工厂使用最优观测值和有利参数，可以观察到LRM对+e−→µ+µ−过程的影响。
The potential for probing the impacts of the left-right symmetric model (LRM) on the processe+e−→ µ+µ−at a proposedZ0-factory is investigated. Under different electron-positron polarization collision modes, we calculate and compare the deviations of various observables in the framework of the LRM from the standard model (SM) predictions, such as the total cross section, the distribution of the transverse momentum of µ−, and the forward-backward charge asymmetry of µ−. In addition, we present the relations between the observables and the LRM parameters. We conclude that it is possible to observe the effects of the LRM on the processe+e−→ µ+µ−by using optimal observables and favorable parameters at aZ0-factory.
