This research program uses computer simulations to study the physics of elementary particles. The method is called lattice field theory and it has become a standard tool for learning about quarks and gluons, which are the building blocks within protons, neutrons, and all other hadrons. Our studies focus on a particular heavy quark, called the bottom quark, because recent experiments in the U.S., Japan, and Europe have discovered several new bottom hadrons. Even more bottom hadrons are anticipated and will be sought in future experiments. The properties of these bottom hadrons can be predicted in advance by using lattice field theory. Lattice field theory can also be applied to other elementary particles, including the Higgs boson. We study aspects of Higgs physics and test ideas for new particles that could augment or replace the standard Higgs theory.

该研究计划使用计算机模拟来研究基本粒子的物理学。 该方法称为晶格场理论，它已成为了解夸克和胶子的标准工具，夸克和胶子是质子、中子和所有其他强子的组成部分。 我们的研究重点是一种特殊的重夸克，称为底夸克，因为美国、日本和欧洲最近的实验发现了几种新的底强子。 预计会有更多的底部强子，并将在未来的实验中寻找。 这些底部强子的性质可以利用晶格场理论提前预测。 晶格场理论也可以应用于其他基本粒子，包括希格斯玻色子。 我们研究希格斯物理学的各个方面，并测试可以增强或取代标准希格斯理论的新粒子的想法。
