Abstract

A major focus in particle physics has been on understanding the interactions of the Higgs boson. Tremendous progress has been made in determining the strength of the couplings of the Higgs boson to fermions and vector bosons, but its self-interaction has yet to be established. Understanding the Higgs self-coupling and the form of the potential function of the Higgs field will illuminate the process by which the Higgs boson acquires a vacuum expectation value and could provide insight into the early Universe and, perhaps, its eventual fate. The most natural way to probe the Higgs self-interaction is via searches for Higgs boson pair (HH) production. Since the Standard Model makes a definite prediction for the Higgs self-coupling, enhanced rates and modified kinematic properties of HH production are a smoking-gun signature for new physics. This article reviews the current experimental status of HH searches, discusses the experimental challenges and limitations, and provides an outlook for the future of the field.

双希格斯生产

粒子物理学的一个重点是了解希格斯玻色子的相互作用。在确定希格斯玻色子与费米子和矢量玻色子的耦合强度方面已经取得了巨大进展，但它的自相互作用尚未确定。了解希格斯自耦合和希格斯场的势函数形式，将阐明希格斯玻色子获得真空期望值的过程，并能让我们深入了解早期宇宙，或许还有它的最终命运。探测希格斯自相互作用的最自然方法是搜索希格斯玻色子对（HH）的产生。由于标准模型对希格斯自耦合做出了明确的预测，因此希格斯玻色子对产生的增强速率和改变的运动学特性是新物理学的烟枪标志。本文回顾了希格斯粒子对搜索的实验现状，讨论了实验挑战和局限，并对该领域的未来进行了展望。

期刊介绍： The Annual Review of Nuclear and Particle Science is a publication that has been available since 1952. It focuses on various aspects of nuclear and particle science, including both theoretical and experimental developments. The journal covers topics such as nuclear structure, heavy ion interactions, oscillations observed in solar and atmospheric neutrinos, the physics of heavy quarks, the impact of particle and nuclear physics on astroparticle physics, and recent advancements in accelerator design and instrumentation. One significant recent change in the journal is the conversion of its current volume from gated to open access. This conversion was made possible through Annual Reviews' Subscribe to Open program. As a result, all articles published in the current volume are now freely available to the public under a CC BY license. This change allows for greater accessibility and dissemination of research in the field of nuclear and particle science.
