摘要/Abstract:

High-energy (HE; ~100 GeV to 100 PeV) and ultrahigh-energy (UHE; >~ 100 PeV) neutrinos are crucial for both particle physics and astrophysics, e.g., offering great opportunities to study neutrino interactions and test the Standard Model and beyond. Neutrino interactions are the cornerstone of all the measurements in neutrino experiments. Studying neutrino interactions also reveals new event classes (e.g., dimuons), offering novel measurement opportunities. In addition, neutrino interaction theory is both interesting and challenging: although neutrinos only participate in weak interactions (and gravity), neutrino interaction studies relevant to the experiments also significantly involve strong interactions and quantum electrodynamics.

报告人简介/Bibliography:

I am currently a Postdoc in Kavli Institute for Cosmological Physics at the University of Chicago. Prior to this, I was a Postdoc (2020-2023) in the Department of Physics and Astronomy at Johns Hopkins University, where I mainly collaborated with Prof. Marc Kamionkowski. I earned my Ph.D. (with Prof. John Beacom) from the Department of Physics at The Ohio State University (2015–2020), where I was also affiliated with the Center for Cosmology and AstroParticle Physics (CCAPP). My primary focus is on theoretical particle astrophysics and cosmology, with particular interests in neutrinos, gamma rays, and dark matter.

周贝目前在芝加哥大学科维里宇宙学物理研究所从事博士后工作。在此之前，他曾在约翰霍普金斯大学物理与天文学系担任博士后（2020-2023），期间主要与Marc Kamionkowski教授合作。他在俄亥俄州立大学物理系获得博士学位（2015-2020），导师是John Beacom教授，同时也隶属于宇宙学与天体粒子物理中心（CCAPP）。他的研究主要集中在理论粒子天体物理学和宇宙学，特别关注中微子、伽马射线和暗物质。
