NBIA Astroparticle Seminar: Sergio Palomares Ruiz

Looking at the Earth's interior with neutrinos is a realistic possibility with current and future neutrino detectors, complementary to geophysics methods, but based purely on weak interactions. In this talk, I will give an overview of the two main approaches to perform Earth tomography with neutrinos: (i) neutrino absorption tomography, based on partial absorption of a neutrino flux in the Earth and (ii) neutrino oscillation tomography, based on coherent Earth matter effects on the neutrino oscillatory pattern. I will first discuss (i) and present the first neutrino tomography of Earth using IceCube data. Then, I will discuss (ii) and, in particular, I will focus on supernova neutrinos with tens of MeV.
