摘要我们开发了一种形式主义，用于计算德西特空间中真空衰变的引力修正，作为亚普朗克微扰膨胀。与重力的非最小耦合可以被编码为有效势。科尔曼弹跳不断变形为霍金-莫斯弹跳，直到它们重合为哈勃常数的临界值。作为一个应用，我们重新考虑暴胀过程中弱电希格斯真空的衰变。我们的真空衰变计算再现并改进了先前通过统计技术计算的最大膨胀哈勃尺度的界限。
A bstractWe develop the formalism for computing gravitational corrections to vacuum decay from de Sitter space as a sub-Planckian perturbative expansion. Non-minimal coupling to gravity can be encoded in an effective potential. The Coleman bounce continuously deforms into the Hawking-Moss bounce, until they coincide for a critical value of the Hubble constant. As an application, we reconsider the decay of the electroweak Higgs vacuum during inflation. Our vacuum decay computation reproduces and improves bounds on the maximal inflationary Hubble scale previously computed through statistical techniques.
