摘要
通过检查4-导数量子引力的Feynman规则,分析理论的各种发散图,发现4-导数量子引力理论的彻底可重整性需要进一步证明,并指出不能期望通过在作用量中加入Riemann张量的更高次幂项来彻底解决引力的重整化问题.
By examining the Feynman rules and divergence loops for the theory of the 4-derivative quantum gravity, we find that the exact renormalizibility of the theory need still to be proven, and show that renormalization of gravity can't be completely resolved by introducing higher.order terms of Riemann tensors in the action.
