精确单回路假真空衰减率

Exact one-loop false vacuum decay rate

Victor Guada, Miha Nemevšek

摘要:

本文讨论了具有两个树能级极小值的四次-四次势中实复标量场在一圈处的精确假真空衰变率。反弹的解决方案是用来计算从两个波动的功能行列式。我们得到了本征值的有限乘积,并消除了平移零模。轨道模式用zeta函数正则化,我们最终得到一个完整的重整化衰变率。我们推导出简单的扩展在薄壁和厚壁的限制,并确定其有效性。

英文摘要:

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.
