This RUI proposal requests support for a program of research in elementary particle theory and phenomenology. Three specific aspects will be studied: (1)flavor symmetry and models with Higgs flavor multiplets; (2) supersymmetric models in warped spacetime; and (3) models for dark matter based upon singlets with respect to gauge and flavor symmetries. The goal of (1) is to derive the observed masses and mixings of quarks and leptons from a more fundamental theory. In the case of (2), the PI hopes to develop the collider phenomenology of certain unified models which predict light exotic states. Item (3) is a real challenge because, apart from gravitation, the singlets hardly interact with normal matter and one needs to know the scattering rates from normal matter in order to detect them directly. The broader impacts of this proposal include the involvement of undergraduates in particle physics research, and the exposure of larger numbers of undergraduates at a predominantly liberal arts college to modern particle physics and its intimate connection with cosmology.

这项瑞的提案要求支持一个基本粒子理论和现象学的研究项目。我们将研究三个具体的方面：(1)味对称性和希格斯味多重态模型；(2)扭曲时空中的超对称模型；(3)基于规范和味对称性的单态暗物质模型。(1)的目的是从一个更基本的理论中推导出观察到的夸克和轻子的质量和混合。在(2)的情况下，PI希望发展预测光奇异状态的某些统一模型的对撞机现象学。第(3)项是一个真正的挑战，因为除了引力，单线态几乎不与正常物质相互作用，人们需要知道正常物质的散射率才能直接探测到它们。这一提议的更广泛影响包括让本科生参与粒子物理研究，以及让一所以文科为主的学院的更多本科生接触到现代粒子物理及其与宇宙学的密切联系。
