论文摘要
我们研究量子重力对在阿贝尔仪表组下收取的手性费米体系的影响。在量子重力的影响下，可以产生量规耦合的有限值，然后又将四弗里术相互作用驱动到关键。我们发现，重力 - 弗里米式相互作用可以保护足够数量的费米子的轻度。另一方面，对于较少数量的费米子，手性对称性可能会被打破，这会与光收费的观察张开。
We study the impact of quantum gravity on a system of chiral fermions that are charged under an Abelian gauge group. Under the impact of quantum gravity, a finite value of the gauge coupling could be generated and in turn drive four-fermion interactions to criticality. We find indications that the gravity-gauge-fermion interplay protects the lightness of fermions for a large enough number of fermions. On the other hand, for a smaller number of fermions, chiral symmetry may be broken, which would be in tension with the observation of light fermions.
