This proposal requests support for a program of research at the interface between cosmology and particle physics. The PI is interested in both developing theoretical ideas to explain major problems in cosmology, especially the problem of dark energy, and, at the same time, using cosmological data from observatories like WMAP to constrain models of cosmology and particle physics. Among the specific topics to be pursued in this proposal are a new model for dark energy and cosmological studies of the string theory landscape. The PI and her collaborators were the first to derive upper and lower bounds on the equation of state for dark energy, and this work has been highly cited and influential. The broader impacts of the proposal include the strong interplay between particle physics and cosmology, and between theory and observational data. Outreach efforts will be made to inform a larger public of students and lay persons about this exciting science which has always caught the public interest and imagination.

该提案请求支持宇宙学和粒子物理学之间的接口研究计划。 PI 感兴趣的是发展理论思想来解释宇宙学中的主要问题，特别是暗能量问题，同时利用 WMAP 等天文台的宇宙学数据来约束宇宙学和粒子物理模型。该提案要追求的具体主题包括暗能量和弦理论景观的宇宙学研究的新模型。 PI 和她的合作者是第一个推导出暗能量状态方程上限和下限的人，这项工作被高度引用并具有影响力。该提案更广泛的影响包括粒子物理学和宇宙学之间以及理论和观测数据之间的强大相互作用。我们将开展宣传工作，让更多的学生和非专业人士了解这一一直引起公众兴趣和想象力的令人兴奋的科学。
