论文摘要
在跨planckian渐近安全框架中嵌入的量规扬川系统中，我们讨论了由肾脏化基团中非交互性红外诱导的固定点驱动的任意小的Yukawa耦合的动态产生。额外的紫外线固定点可以保证该理论仍然可以很好地定义至无限的高度。我们将此机制应用于与右中微子扩展的标准模型的Yukawa耦合，发现与当前的质量测定量和混合角有关，dirac中微子与正常的质量顺序相吻合。我们通过将相同的机制应用于带有无菌的新物体模型来概括讨论，在那里我们自然会产生微弱的Yukawa互动，以通过冻结正确的遗物丰度复制。
In gauge-Yukawa systems embedded in the framework of trans-Planckian asymptotic safety we discuss the dynamical generation of arbitrarily small Yukawa couplings driven by the presence of a non-interactive infrared-attractive fixed point in the renormalization group flow. Additional ultraviolet-attractive fixed points guarantee that the theory remains well defined up to an infinitely high scale. We apply this mechanism to the Yukawa couplings of the Standard Model extended with right-handed neutrinos, finding that asymptotically safe solutions in agreement with the current experimental determination of the masses and mixing angles exist for Dirac neutrinos with normal mass ordering. We generalize the discussion by applying the same mechanism to a new-physics model with sterile-neutrino dark matter, where we generate naturally the feeble Yukawa interaction required to reproduce via freeze-in the correct relic abundance.
