 Title“Studying the Earth with neutrinos – Borexino and Theia”
 AbstractGeoneutrinos are antineutrinos originating from the radioactive decays of long-lived isotopes naturally present in the crust and mantle. Geoneutrinos can be used as a unique direct probe in order to determine the amount of long-lived radioactive elements inside our planet and to constrain the radiogenic contribution to the terrestrial heat. Up to date, only two experiments in the world, Borexino (Italy) and KamLAND (Japan), have observed a combined total of 216.6 geoneutrinos in the span of 12 years and 14 years, correspondingly. Theia-25, a proposed novel neutrino detector, will coincidentally observe the similar number of geoneutrinos within just one year of data-taking. In this talk, I will give an overview of the geoneutrino field, concentrating on Borexino measurements, and Theia sensitivity studies.
