Probing the Physics of the Hierarchy Problem

理论基本粒子物理学和宇宙学的一个双管齐下的项目将研究基本粒子的质量来源和现在主导宇宙的能量来源。对于前者，研究将确定如何使用高能对撞机设备的数据来揭示希格斯玻色子与物质相互作用的方式。由此，我们将了解是否有一个以上的希格斯玻色子，以及希格斯玻色子如何为其他粒子产生质量。在后一方面，越来越多的证据表明，宇宙中的大多数能量都有一种独特而未知的形式。将建立模型来解释这些数据，并根据不断增长的数据进行测试。是什么赋予了粒子质量，又是什么赋予了宇宙质量，这两个问题至关重要，将成为未来十年理论和实验工作的中心。

A two-pronged program in theoretical elementary particle physics andcosmology will study the source of mass for elementary particles and thesource of energy which now dominates the universe. For the former, studieswill be made to determine how data from high-energy collider facilitiescan be used to unravel the way in which the Higgs boson interacts withmatter. From this we will learn whether there is more than one Higgs bosonand how the Higgs boson(s) generate masses for other particles. On thelatter front, there is mounting evidence that most of the energy in theuniverse has a unique and unknown form. Models will be built to explainthis data and will be tested against the growing body of data. The twinquestions of what gives particles their mass and what gives the universeits mass are fundmentally important and will be at the center oftheoretical and experimental work for the coming decade.
