RUI: Role of Scalar Mesons in Low-Energy QCD and their Connections to Non-Perturbative Higgs Dynamics

本文的目的是研究2GeV以下轻标量介子的性质和夸克亚结构。该方法是着眼于强相互作用的有效模型，如线性和非线性手征拉格朗日。希望是从潜在的夸克的角度来深入了解这些介子的构成。 例如，一些轻介子被发现是2和4夸克态的混合物。 希望对标量介子有更好的理解，将有助于揭示电弱对称性破缺和D介子的性质，这些都是BaBar合作组和费米实验室研究的结果。这项研究将涉及大学生在调查的各个计算方面。

The purpose of this proposal is to investigate the properties and quark substructure of the light scalar mesons below two GeV. The methodology is to look at effective models of strong interactions such as linear and non-linear chiral lagrangians. The hope is to gain insight into the makeup of these mesons in terms of the underlying quarks. For example, some of the light mesons have been found to be a mixture of two and 4 quark states. It is hoped that a better understanding of the scalar mesons will shed light on electroweak symmetry breaking and on the properties of the D mesons which have been investigated by both the BaBar Collaboration and Fermilab experiments. The research will involve undergraduates in various computational aspects of the investigation.
