AI总结:
本文探讨了高阶导数引力项在隧穿过程中的物理特征,特别是Gauss Bonnet项在4D Higgs真空衰变中可能显现的可观测信号及其物理可及性。
摘要:
从量子引力角度看,引力作用量中的高阶导数项是自然的,但被认为会导致适定性缺失。Gauss Bonnet项具有二阶运动方程,但在4D中不影响引力动力学,因此人们可能预期它没有物理相关性。我们讨论了这些特征如何在隧穿过程中显现,以及它们是否可能在Higgs真空衰变中具有物理可及性。
英文摘要:
Higher derivative terms in the gravitational action are natural from the perspective of quantum gravity, but are perceived as leading to a lack of well-posedness. The Gauss Bonnet term has second-order equations of motion, but does not impact gravitational dynamics in 4D, so one might expect that it is not physically relevant. We discuss how signatures can show up in tunnelling processes and whether these will likely be physically accessible in Higgs vacuum decay.
