Origin and Probes of Baryonic and Dark Matter

PI计划探索如何使用各种天文工具通过暗物质微弱的发光现象来探测暗物质。当暗物质粒子成对湮灭或衰变时，就会产生光子和其他辐射粒子，可以用伽马射线、x射线、光学和射电望远镜探测到。PI还将研究暗物质的微观粒子特征如何影响宇宙结构的演变。并展示这可能如何解决宇宙学和天体物理学中的一些悬而未决的问题。重子物质（重子生成）的产生问题将在其与标准模型之外的粒子物理设置（如超对称）的关系中进行分析。重子发生机制的印记可以出现在各种各样的领域，这些领域将在提议的研究中探索，例如用对撞机搜索新粒子，早期宇宙的引力波和基本粒子的奇异特性。PI将参与加州大学圣克鲁兹分校的SCIPP和UCSC物理推广项目，该项目专注于大学预科学生及其教师，其中包括来自圣克鲁斯县南部和内陆地区的大量代表性不足的群体。后一项活动得到了QuarkNet、GLAST和EPO的部分支持。

The PI proposes to explore how one might detect dark matter through its faint luminous manifestations using various astronomical tools. When dark matter particles pair-annihilate, or if they decay, photons and other radiating particles are produced and can be detected with gamma-ray, X-ray, optical and radio telescopes. The PI will also study how the microscopic particle features of dark matter effect the evolution of structure in the Universe,. and show how this might solve some open questions in cosmology and astrophysics. The issue of the generation of baryonic matter (baryogenesis) will be analyzed in its relationship with particle physics setups beyond the Standard Model, such as Supersymmetry. Imprints of the baryogenesis mechanism can emerge in a wide variety of fields that will be explored in the proposed research, such as searches for new particles with colliders, gravitational waves from the Early Universe and exotic properties of elementary particles. The PI will participate in SCIPP and UCSC Physics outreach programs at UCSC which concentrates on pre-college students and their teachers which includes a large component of under-represented groups from the southern and inland parts of Santa Cruz County. This latter activity is partially supported by QuarkNet, GLAST and EPO.
