通过对希格斯质量进行量纲分析，人们可以预测新的物理相互作用会在1TeV量级上产生希格斯质量。这些相互作用可能是什么的问题被称为量规层次问题。解决这个问题一直是过去几十年粒子物理学的中心目标。传统的解决方案引入了质量低于1TeV的新粒子，但现在这一预测受到了实验的挑战。在这篇文章中，我回顾了最近解决这个问题的新方法，这些方法不需要在TeV质量尺度上有新的粒子。我首先讨论弛豫方法，即希格斯质量是动力学的，并且在其势的绝对最小值下是小的。然后，我讨论了历史方法，即关于膨胀和/或膨胀后再加热的细节会导致希格斯质量比其他情况下的预期要小。最后，我讨论了使用条件概率的解决方案，根据宇宙常数很小的事实，条件会自动导致人们选择希格斯质量也很小的真空。
Applying dimensional analysis to the Higgs mass leads one to predict new physics interactions that generate this mass at a scale of the order of 1 TeV. The question of what these interactions could be is known as the gauge hierarchy problem. Resolving this question has been a central aim of particle physics for the past few decades. Traditional solutions introduce new particles with masses below 1 TeV, but that prediction is now challenged by experiment. In this article, I review recent new approaches to the problem that do not require new particles at the TeV mass scale. I first discuss the relaxation approach, whereby the Higgs mass is made dynamical and is small at the absolute minimum of its potential. I then discuss the historical approach, whereby details about inflation and/or reheating after inflation cause the Higgs mass to be smaller than otherwise expected. Finally, I discuss solutions that use conditional probability, whereby conditioning on the fact that the cosmological constant is small automatically leads one to select vacua where the Higgs mass is also small.
