双峰-三重峰分裂问题的一个宇宙学解

A Cosmological Solution to the Doublet-Triplet Splitting Problem

Csaba Csaki, Raffaele Tito D'Agnolo, Eric Kuflik, Pablo Sesma

AI总结:

提出一个基于两个类轴子粒子动力学的宇宙学模型,同时解决大统一理论的双峰-三重峰分裂、电弱层级和强CP问题,留下可探测的弱耦合痕迹。

摘要:

我们提出一个模型,该模型同时解决大统一理论中的双峰-三重峰分裂问题、电弱层级问题和强CP问题。该机制基于两个类轴子粒子的动力学,如果三重峰是轻的或具有真空期望值,或者如果双峰是重的或不具有真空期望值,这些粒子会在QCD相变时导致宇宙收缩。低能下留下的唯一痕迹就是这两个类轴子粒子。它们与标准模型弱耦合,可能在未来轴子实验或通过中子电偶极矩测量与模糊暗物质天体物理探测相结合的方式被探测到。

英文摘要:

We propose a model that provides a simultaneous solution to the doublet-triplet splitting problem of grand unified theories, the electroweak hierarchy problem and the strong CP problem. The mechanism is based on the dynamics of two axion-like particles that would crunch the universe at the time of the QCD phase transition if triplets were light or had a VEV or if doublets were heavy or did not have a VEV. The only trace left at low energies are these two axion-like particles. They are weakly coupled to the Standard Model and could be detected at upcoming axion experiments or by a combination of neutron EDM measurements and the astrophysical detection of fuzzy dark matter.
