Abstract

A bstract The detection of a stochastic Gravitational Wave (GW) background sourced by a cosmological phase transition would allow us to see the early Universe from a completely new perspective, illuminating aspects of Beyond the Standard Model (BSM) physics and inflationary cosmology. In this study, we investigate whether the evolution of the scalar potential of a minimal SM extension after inflation can lead to a strong first-order phase transition. In particular, we focus on a BSM spectator scalar field that is non-minimally coupled to gravity and has a dynamical double-well potential. As inflation ends, the potential barrier diminishes due to the evolution of the curvature scalar. Therefore, a phase transition can proceed through the nucleation of true-vacuum bubbles that collide as they fill the Universe and produce GWs. We consider high and low scales of inflation, while also taking into account a kination period between inflation and the onset of radiation domination. With this prescription, we showcase a proof-of-concept study of a new triggering mechanism for BSM phase transitions in the early Universe, whose GW signatures could potentially be probed with future detectors.

探测到宇宙相变产生的随机引力波(GW)背景，将使我们从一个全新的角度来看待早期宇宙，并阐明超越标准模型(BSM)物理学和暴胀宇宙学的各个方面。在本研究中，我们研究了膨胀后最小SM扩展的标量势的演化是否会导致强一阶相变。我们特别关注了一个非最小引力耦合且具有动态双阱势的BSM旁观者标量场。当膨胀结束时，势垒由于曲率标量的演化而减小。因此，相变可以通过真真空气泡的成核进行，当它们充满宇宙并产生gw时，这些气泡会发生碰撞。我们考虑了高和低规模的通货膨胀，同时也考虑了通货膨胀和辐射统治开始之间的间隔期。有了这个处方，我们展示了早期宇宙中BSM相变的新触发机制的概念验证研究，其GW特征可能会被未来的探测器探测到。

期刊介绍： The aim of the Journal of High Energy Physics (JHEP) is to ensure fast and efficient online publication tools to the scientific community, while keeping that community in charge of every aspect of the peer-review and publication process in order to ensure the highest quality standards in the journal. Consequently, the Advisory and Editorial Boards, composed of distinguished, active scientists in the field, jointly establish with the Scientific Director the journal''s scientific policy and ensure the scientific quality of accepted articles. JHEP presently encompasses the following areas of theoretical and experimental physics: Collider Physics Underground and Large Array Physics Quantum Field Theory Gauge Field Theories Symmetries String and Brane Theory General Relativity and Gravitation Supersymmetry Mathematical Methods of Physics Mostly Solvable Models Astroparticles Statistical Field Theories Mostly Weak Interactions Mostly Strong Interactions Quantum Field Theory (phenomenology) Strings and Branes Phenomenological Aspects of Supersymmetry Mostly Strong Interactions (phenomenology).
