我们计算了从量子引力到局部de Sitter背景下无质量最小耦合标量的自质量平方的单圈修正。计算使用维度正则化进行，并通过减去四阶BPHZ（Bogoliubov-Parasiuk-Hepp-Zimmerman）反项进行重正化。我们的结果应该确定量子引力环修正是否可以显着改变标量暴胀的动力学。
We compute the one loop corrections from quantum gravity to the self-mass-squared of a massless, minimally coupled scalar on a locally de Sitter background. The calculation was done using dimensional regularization and renormalized by subtracting fourth order BPHZ (Bogoliubov-Parasiuk-Hepp-Zimmerman) counterterms. Our result should determine whether quantum gravitational loop corrections can significantly alter the dynamics of a scalar inflaton.
