- Graduate Program Event
- high-energy cosmic neutrinos as a window to the Universe
- Time: 2:30 pm
- Place: 2241 Chamberlin Hall and zoom link below
- Speaker: Qinrui Liu, Physics PhD Graduate Student
- Abstract: The Universe is a natural laboratory for us to investigate physics. Neutrinos of cosmic origin are an excellent messenger exploring astronomy, cosmology and particle physics, for they are tiny, neutral and weakly-interacting, which leads to undeflected and nearly unscathed travel across the Universe to Earth from their sources. They are an important piece in solving several significant open questions in physics such as the mystery of cosmic ray accelerators, as high-energy cosmic neutrinos play the role of a smoking-gun signal of hadronic interactions of cosmic rays, and the nature of dark matter as neutrinos can be produced in dark matter annihilation or decay, providing an indirect signature. The IceCube experiment discovered TeV-PeV neutrinos of astrophysical origin with an energy flux comparable to that of gamma rays and cosmic rays. One mission that comes afterwards is to identify where those neutrinos come from and how they are produced. I will discuss the search for their astrophysical sources, emphasizing the efforts to identify sources in our Galaxy from candidates pulsar wind nebulae and X-ray binaries with IceCube data. Like atmospheric neutrinos, the beam of cosmic neutrinos provides us with excellent opportunities to study physics beyond the standard model, e.g. dark matter annihilation and decay. The indirect searches of dark matter will be discussed with a focus on a new computation of neutrino signals from dark matter accumulated in multiple celestial environments.

- C3: An Advanced Concept for a e+e- Linear Collider
- Time: 4:00 pm - 5:00 pm
- Place: Zoom:
- Speaker: Prof. Emilio Nanni, SLAC National Accelerator Laboratory, Stanford
- Abstract: The goal of a next-generation e+e- collider is to carry out precision measurements to per-cent level of the Higgs boson properties that are not accessible at the LHC and HL-LHC. In this talk we will present the study of a new concept for a high gradient, high power accelerator with beam characteristics suitable to study the Higgs boson, the Cool Copper Collider (C3), with the goal of significantly reducing capital and operating costs. C3 is based on the latest advances in rf accelerator technology and utilizes optimized cavity geometries, novel rf distribution and operation a cryogenic temperatures to allow the linear accelerator to achieve high accelerating gradients while maintaining overall system efficiency. We will present the latest demonstrated performance of prototype accelerators and highlight the future development path for C3.
