9722546 Yuan A basic goal of physics is to explain the workings of the natural universe with the most simple, elegant theory possible. In addition, a good theory must also make concrete predictions that can be tested by experiments. In these regards, the standard model of particle physics has been an outstanding success. However, there are certain questions that the standard model cannot address, the most basic of which is the origin of the particle masses. To go beyond the standard model, we need input from new high energy colliders, such as the Large Hadron Collider, which is currently under construction in Europe. In this project the group at MSU and colleagues at Tsinghua University, Beijing, will study the problem of mass generation, and how it can be probed by these new colliders. Theoretical arguments predict that new physics must arise at these high energies. In this project, both specific models will be used as well as model-independent analyses to show how the data can shed light on the more complete theory. Both groups bring complementary expertise to bear on the problem; both groups will involve graduate students in the research programs.

9722546元 物理学的一个基本目标是用最简单、最优雅的理论来解释自然宇宙的运作。 此外，一个好的理论还必须做出可以通过实验检验的具体预测。 在这些方面，粒子物理学的标准模型是一个杰出的成功。 然而，标准模型无法解决某些问题，其中最基本的是粒子质量的起源。 为了超越标准模型，我们需要来自新的高能对撞机的输入，例如目前正在欧洲建造的大型强子对撞机。 在这个项目中，密歇根州立大学的研究小组和北京清华大学的同事将研究质量产生的问题，以及如何通过这些新的对撞机进行探测。 理论论证预言，新的物理学必然会在这些高能量下产生。 在这个项目中，将使用两个特定的模型以及模型独立的分析，以显示数据如何揭示更完整的理论。 两个小组都带来了互补的专业知识来解决这个问题;两个小组都将让研究生参与研究项目。
