This proposal seeks to understand what lies beyond the standard model of particle physics. This is a multi-front approach connected to experiments at the intensity, energy, and cosmic frontiers. The overarching areas I will be studying involve (i) dark matter, neutrinos, and their possible connection; (ii) the matter asymmetry of the Universe; (iii) light, ultra weakly coupled new physics; and (iv) new physics at the energy frontier to understand the origin of the weak scale. My approach with all of these subjects will be to forge new directions, broadening our approaches and ensuring that we are not overlooking any possibilities. I am, and will continue to be, tightly coupled to experiment and will help to devise new experimental tests of physics beyond the standard model. Although we have not yet found new physics in the form we expected at the energy frontier, our exploration is far from complete. This is a deep problem and it is entirely possible that nature does not conform to our first hypotheses about what is beyond the standard model. The community that works on physics beyond the standard model has come to recognize this more in the past few years. My research has helped guide that realization and will continue to push the field where it needs to go. An underlying theme behind this research is the interdisciplinary nature of it, bringing together somewhat disparate fields. This is largely done by constructing complete, self-consistent models that tie different observables together across the various frontiers. Related to this is the development of new experimental approaches and techniques. Part of my expertise lies in identifying these and working with experimentalists to bring these to fruition. It is crucial to identify ways to probe physics beyond the standard model in the near term. Additionally, this proposal will help in developing young scientists in Canada, through involvement in research projects, and in increasing the interest and appreciation of science in the general public. The work described in this proposal will connect with the larger physics community in Canada and across the world. There will be ample opportunity for training of HQP. I will be poised to help lead the community in the direction that experiment takes us.

该提案旨在了解粒子物理学标准模型之外的内容。这是一种与强度、能量和宇宙前沿实验相关的多前沿方法。 我将研究的首要领域包括（i）暗物质、中微子及其可能的联系； (ii) 宇宙的物质不对称性； (iii) 光、超弱耦合新物理； (iv) 能源前沿的新物理学，以了解弱尺度的起源。我对所有这些主题的处理方法将是开辟新的方向，拓宽我们的方法并确保我们不会忽视任何可能性。我现在并将继续与实验紧密结合，并将帮助设计超出标准模型的新物理实验测试。 尽管我们尚未在能源前沿发现我们所期望的新物理形式，但我们的探索还远未完成。这是一个深层次的问题，自然完全有可能不符合我们关于标准模型之外的东西的第一个假设。在过去的几年里，致力于超越标准模型的物理学界越来越认识到这一点。我的研究帮助引导了这一认识，并将继续推动该领域发展。这项研究背后的一个基本主题是它的跨学科性质，它将一些不同的领域聚集在一起。这主要是通过构建完整的、自洽的模型来完成的，这些模型将不同领域的不同可观测值联系在一起。与此相关的是新实验方法和技术的发展。我的部分专业知识在于识别这些并与实验人员合作以实现这些目标。在短期内找到超越标准模型来探索物理学的方法至关重要。此外，该提案将通过参与研究项目帮助培养加拿大的年轻科学家，并提高公众对科学的兴趣和欣赏。该提案中描述的工作将与加拿大和世界各地更大的物理学界联系起来。总部将有充足的培训机会。我将准备好帮助带领社区朝着实验所引导的方向前进。
