The main natural antineutrino sources expected atTheia-25 at SURF are radioactive elements in the crust and mantle of the Earth. Geoneutrinos are electron flavour antineutrinos emitted inside the Earth, in the radioactive decays of HPEs with lifetimes comparable with the age of the Earth(4.54...
Now, a team of scientists has a provocative new proposal: Theia's remains can be found in two continent-size layers of rock buried deep in Earth's mantle. Who made Earth? Formation. When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when ...
more recent work [38] points out the non-unitarity cannot explain the tension with the bounds on non-unitarity parameters from the combination of short- and long-baseline data. Similar thing happens for the light sterile neutrino scheme [39]. Whether this tension is truly new physics or not ...
Finally, although simulation uncertainties and a terrestrial contribution to Moon formation enhance the fraction of Theia analogs consistent with the canonical giant impact hypothesis, this fraction still remains in the 5–8% range.doi:10.1016/j.icarus.2015.06.019Kaib, Nathan A....
