School of Physics: HEPCo Weekly Seminar Series Title of talk Shining the Neutrino Flashlight into the Darkest Places تاباندن پرتو نوترینو به تاریک‌ترین (ناشناخته ترین) مکان‌ها Date and time Tuesday, June 3rd, 2025 (13 Khordad), 2:00 pm (Tehran zone) Link https://www.skyroom.online/ch/schoolofphysics/highenergyseminar Abstract The most phenomenologically important properties of neutrinos are the facts that they don't interact with regular matter very much and that they change which charged lepton they like to interact with during propagation. The presence of matter does modify the propagation of neutrinos, somewhat, and I use this fact along with known oscillation parameters to probe environments that cannot be otherwise directly probed. In particular, I will show how low energy atmospheric neutrinos provide information about the Earth's core and that this can be determined by DUNE. I will also use current data from solar neutrino experiments, constrained by reactor neutrino data, to determine the density in the core of the Sun via neutrinos for the first time, as well as future sensitivities.
