我们评估一个循环的量子引力修正的共形耦合（CC）标量自质量平方的局部德西特背景。在本文中，我们只考虑自质量平方的共形-共形相互作用部分。这是对前一篇文章[E. O. Kahya和R. P. Woodard，Phys.Rev.D76，124005（2007），arXiv：0709.0536]，并且我们将在后续论文中添加最小共形部分以完成一个循环阶的完整自质量平方。计算使用维正则化和结果完全重整化吸收发散与counterterterms。有限的结果可以引起量子修正的CC标量模式功能，因此，他们的功率谱。
We evaluate one loop quantum gravity corrections to the conformally coupled (CC) scalar self-mass-squared on a locally de Sitter background. In this paper we consider only the conformal-conformal interaction part of the self-mass-squared. This complements the minimal-minimal part worked out in the previous paper [E. O. Kahya and R. P. Woodard, Phys. Rev. D 76, 124005 (2007), arXiv: 0709.0536], and we will add the minimal-conformal part in a follow-up paper to complete the full self-mass-squared at one loop order. The computation is performed using dimensional regularization and the results are fully renormalized by absorbing divergences with counterterms. The finite results can give rise to quantum corrections to the CC scalar mode functions and therefore to their power spectra.
