This award funds the research of Professors Paolo Gondolo and Pearl Sandick at the University of Utah. The nature of more than 80% of the matter in the universe is unknown. To discover the nature of this so-called dark matter is a major open question in physics, astrophysics, and cosmology. Dark matter has been detected only by means of the gravity it generates, and has properties that are completely different from those of any other known physical matter. Establishing the nature of dark matter may have implications as important as the Copernican revolution that shifted the Earth's place in the Universe away from its center, this time by relegating the material substance humans are made of to a minority component. Research in this area advances the national interest by promoting the progress of science in one of its most fundamental aspects: discovering the nature and composition of our physical universe. In their research, Professors Gondolo and Sandick aim to further our understanding of dark matter and our ability to sort viable dark-matter models on the basis of their observable effects. This project is also envisioned to have significant broader impacts, including educating and exciting the local non-academic community about science and training early-career scientists. The project will also support a long-standing and successful outreach program at a local science museum and in local schools that reaches thousands of young students with the goal of attracting them to science in a fun, energetic, and engaging way. At the same time, this project supports efforts to recruit and retain talented women and minorities in the physical sciences through a suite of outreach and professional-development programs at the University of Utah, in the broader community, and at the national level.Technically, Professors Gondolo and Sandick will conduct individual research programs with elements in common. They will (a) explore theoretical explanations for the dark matter in the Universe and for theories of new particle physics beyond the Standard Model of particle physics; (b) better understand the assumptions and the uncertainties inherent in the relevant calculations; and (c) determine and suggest robust strategies for the identification of dark matter and, potentially, other new physics. These objectives will be achieved through phenomenological studies of collider and dark-matter signatures in the Minimal Supersymmetric Standard Model and in simplified models, the development of the DarkSUSY software to address generic weakly-interacting massive particle (WIMP) models, and the pursuit of a minimal number of assumptions in the particle physics and astrophysics of dark matter through astrophysics-independent methods and general interaction lagrangians.

该奖项资助了犹他州大学的Paolo Gondolo和Pearl Sandick教授的研究。宇宙中超过80%的物质的性质是未知的。发现这种所谓的暗物质的本质是物理学、天体物理学和宇宙学中的一个主要开放问题。暗物质只能通过它产生的引力来检测，并且具有与任何其他已知物理物质完全不同的性质。确定暗物质的性质可能具有与哥白尼革命一样重要的意义，哥白尼革命将地球在宇宙中的位置从其中心转移，这一次是通过将构成人类的物质降为少数成分。这一领域的研究通过促进科学在其最基本的方面之一的进步来促进国家利益：发现我们物质宇宙的性质和组成。在他们的研究中，Gondolo教授和Sandick教授的目标是进一步了解暗物质，以及我们根据可观察到的效应对可行的暗物质模型进行分类的能力。该项目还设想产生更广泛的影响，包括教育和激发当地非学术界对科学和培训早期职业科学家的兴趣。该项目还将支持当地科学博物馆和当地学校的一个长期而成功的推广计划，该计划将覆盖数千名年轻学生，目标是以有趣，充满活力和引人入胜的方式吸引他们参与科学。 与此同时，该项目支持通过一套在犹他州大学，在更广泛的社区和国家层面的推广和专业发展计划，在物理科学领域招募和留住有才华的女性和少数民族的努力。在技术上，贡多洛教授和桑迪克教授将进行具有共同元素的个人研究计划。 他们将（a）探索宇宙中暗物质的理论解释和粒子物理学标准模型之外的新粒子物理学理论;（B）更好地理解相关计算中固有的假设和不确定性;（c）确定和建议确定暗物质和可能的其他新物理学的稳健战略。这些目标将通过在最小超对称标准模型和简化模型中对对撞机和暗物质特征进行唯象研究，开发DarkSUSY软件以解决一般弱相互作用大质量粒子（WIMP）模型，以及通过天体物理学独立方法和一般相互作用拉格朗日函数在粒子物理学和暗物质天体物理学中追求最少数量的假设来实现。
