我们揭示了四维手征规范汤川理论的动力学特征的几个标量自由度变换根据不同的代表性的基础规范群。我们考虑广义Georgi-Yankielowicz和Bars-Yankielowicz理论。我们确定，在微扰理论中的最大已知阶，这些理论的相图，并进一步解开他们的紫外渐近性质，根据他们是否是渐近自由或安全。因此，我们扩展了一些理论，已知是基本的威尔逊意义上的手征规范理论与标量的情况下。
We unveil the dynamics of four dimensional chiral gauge-Yukawa theories featuring several scalar degrees of freedom transforming according to distinct representations of the underlying gauge group. We consider generalized Georgi-Glashow and Bars-Yankielowicz theories. We determine, to the maximum known order in perturbation theory, the phase diagram of these theories and further disentangle their ultraviolet asymptotic nature according to whether they are asymptotically free or safe. We therefore extend the number of theories that are known to be fundamental in the Wilsonian sense to the case of chiral gauge theories with scalars.
