弯曲时空有效场理论(cEFT)的自顶向下方法--理论与实例

Top-down approach to the curved spacetime effective feld theory (cEFT) -- theory and examples

Łukasz Nakonieczny

摘要:

有效场论(EFT)在现代粒子物理学的各个方面,无论是理论、现象学还是实验,都是一个具有巨大价值的工具。在本文中,我将展示如何扩展系统的自上而下的方法来建设EFT提出的村山仁(LBL,伯克利)和分别由约翰埃利斯(国王学院伦敦)集团弯曲的时空。为了达到这个目的,我将利用热核方法,到目前为止,它被广泛地用于获得弯曲时空中的单圈有效作用量。在介绍了形式主义之后,我将讨论它在引力对希格斯有效势稳定性的影响问题上的应用。

英文摘要:

The effective field theory (EFT) turns out to be an instrument of an immense value in all aspects of modern particle physics being theory, phenomenology or experiment. In the paper I will show how to extend the systematic top down approach to construction of the EFT proposed by Hitoshi Murayama (LBL, Berkeley) and separately by John Ellis (King's Coll. London) groups to the curved spacetime. To this end, I will take advantage of the heat kernel method so far extensively used in obtaining the one-loop effective action in curved spacetime. After an introduction of the formalism I will discuss its application to the problem of an influence of gravity on the stability of the Higgs effective potential.
