标题： Gravity and the Higgs boson mass

摘要： 根据量子场论中的通常计算，无论是在平直时空还是弯曲时空中，标量粒子的质量$m^2$对理论的终极尺度，即紫外物理截断$\Lambda$都具有二次敏感性。 在本工作中，关注路径积分测度以及$\Lambda$的引入方式，我们计算了在非平凡引力背景上标量场的一环有效作用量$\Gamma^{1l}$。 我们发现$m^2$仅对$\Lambda$具有（温和的）对数敏感性。 这是在不借助理论的超对称嵌入，也不借助如维度正规化或Zeta函数正规化等幂律发散通过构造被消除的正规化方案的情况下得到的。 鉴于本工作的结果，我们最终推测如何接近闵可夫斯基极限。 显示英文摘要

摘要： According to usual calculations in quantum field theory, both in flat and curved spacetime, the mass $m^2$ of a scalar particle is quadratically sensitive to the ultimate scale of the theory, the UV physical cutoff $\Lambda$. In the present work, paying attention to the path integral measure and to the way $\Lambda$ is introduced, we calculate the one-loop effective action $\Gamma^{1l}$ for a scalar field on a non-trivial gravitational background. We find that $m^2$ presents only a (mild) logarithmic sensitivity to $\Lambda$. This is obtained without resorting to a supersymmetric embedding of the theory, nor to regularization schemes (as dimensional or zeta-function regularization) where power-like divergences are absent by construction. In view of the results of the present work, we finally speculate on the way the Minkowski limit should be approached.
