论文摘要
我们在一个循环中讨论一个精确的假真空衰减速率，用于具有两个树级最小值的四分位势中的真实和复杂的标量场。弹跳溶液用于计算两个波动中的功能决定因素。我们获得特征值的有限乘积并删除转化零模式。轨道模式通过Zeta函数进行正规化，我们最终得到了完整的重质衰减率。我们在薄壁限制中得出简单的扩展，并确定其有效性。
We discuss an exact false vacuum decay rate at one loop for a real and complex scalar field in a quartic-quartic potential with two tree-level minima. The bounce solution is used to compute the functional determinant from both fluctuations. We obtain the finite product of eigenvalues and remove translational zero modes. The orbital modes are regularized with the zeta function and we end up with a complete renormalized decay rate. We derive simple expansions in the thin and thick wall limits and determine their validity.
