标题： Vacuum decay and internal symmetries

摘要： 我们研究内部对称性在亚稳假真空通过气泡核化衰变中的影响。 与连续内部对称性破缺相关的关于回波解的零模会导致进入某些对称性被自发破缺的真空中隧穿率的增强。 我们发展了一个通用的形式理论，用于评估这些零模在平坦和弯曲时空中的气泡核化速率的影响。 显示英文摘要

摘要： We study the effects of internal symmetries on the decay by bubble nucleation of a metastable false vacuum. The zero modes about the bounce solution that are associated with the breaking of continuous internal symmetries result in an enhancement of the tunneling rate into vacua in which some of the symmetries of the initial state are spontaneously broken. We develop a general formalism for evaluating the effects of these zero modes on the bubble nucleation rate in both flat and curved space-times.
