Physics beyond the Standard Model with IceCube

星期四 2025-04-03 09:30 - 10:30 Dr.AnnaPollmann, Chiba University Tsung-Dao Lee InstituteN6F-N600 - Lecture Room

Abstract
The IceCube neutrino observatory is a neutrino telescope situated near the South Pole in Antarctica. A cubic kilometer of ice is instrumented with optical modules sensitive to photons. When high energetic particles produce light in interactions with the ice, the signature can be recorded and used for reconstruction of the primary particle. The design of IceCube not only facilitates the detection of astrophysical neutrinos up to PeV energies but also the direct and indirect probe of physics beyond the Standard Model with leading sensitivities. Exotic particles which can penetrate through the ice sheet or even the entire Earth can be measured directly, these include magnetic monopoles, Q-Balls, partially charged particles and many more. Also, many dark matter candidates are indirectly searched for by investigating its effect on neutrino spectra as well as arrival directions.
I will give an overview of IceCube’s most recent results in regards of particle physics incl. beyond Standard Model physics. Particularly I will present about my own research that aims to open novel detection channels for exotic physics in IceCube.
