研究了暴胀过程中衰变到不同真空的相对几率。计算是在单场慢滚势使用随机通货膨胀形式主义。各种情况下进行了调查，包括从当地的最大值的潜力和逃避当地的最小值。在后一种情况下，我们的结果与Hawking和Moss的结果一致，但适用于任何势。衰变率也计算，并与多个最小值和最大值的一般潜在的情况下进行了讨论。
The relative probability to decay towards different vacua during inflation is studied. The calculation is performed in single-field slow-roll potentials using the stochastic inflation formalism. Various situations are investigated, including falling from a local maximum of the potential and escaping from a local minimum. In the latter case, our result is consistent with that of Hawking and Moss, but is applicable to any potential. The decay rates are also computed, and the case of a generic potential with multiple minima and maxima is discussed.
