Theoretical Particle Physics, Astrophysics and Cosmology

PI: Glennys Farrar研究所：纽约大学该研究项目将解决对我们的宇宙概念至关重要的问题：暗物质是由什么组成的？什么是暗能量？暗物质和暗能量会相互作用吗？为什么暗物质的丰度与普通物质的丰度差不多，而在传统理论中它们是不相关的？事实上，为什么宇宙中还会有普通物质呢？除了我们生活的3个维度之外，还有其他维度吗？我们对它们的结构和性质能说些什么？特别是PI将开发一个半解析宇宙射线阵雨模拟器（SENECA）。一种新的暗物质候选者（h -双重子）将基于轻胶子的存在进行研究。该研究将包括通过暗物质质量对精粹场的依赖，对暗物质（DM）和暗能量（DE）耦合的后果进行详细而深入的检查。PI还将检验那些能够在没有重子数违反的情况下产生标准模型重子不对称的模型，并研究是否可以将DM识别为不同膜上的镜像普通物质。

PI: Glennys Farrar Institute: New York University The research program will address questions that are fundamental to our conception of the universe: What is dark matter composed of? What is the dark energy? Do dark matter and dark energy interact with each other? Why is the abundance of dark matter about equal to that of ordinary matter, when in conventional theory they are unrelated? Indeed, why is there any ordinary matter left in the Universe at all? Are there more dimensions than the 3 we live in, and what can we say about their structure and properties? In particular the PI will develop a semi-analytic cosmic ray shower simulator (SENECA). A new candidate for dark matter (the H-dibaryon) which is based on the existence of light gluinos will be studied. The research will include a detailed and intensive examination of the consequences of coupling dark matter (DM) and dark energy (DE) through a dependence of DM mass on a quintessence field. The PI will also examine models that can generate an asymmetry for standard model baryons without baryon number violation and investigate whether one can identify DM as mirror ordinary matter on a different brane.
