Neutrinos matter. Can nEXO show that they antimatter too?

The discovery of neutrino mass is the only observed phenomenon that contradicts the standard model of particle physics. The explanation of the origin of the tiny neutrino masses poses an incredible hypothesis: what if neutrinos and antineutrinos are the same? This would have groundbreaking implications for matter generation, and could explain the matter-antimatter asymmetry observed in the universe. It also predicts a rare nuclear decay, neutrinoless double beta decay, with a half life of at least 10^26 years. The nEXO experiment aims to detect this rare decay and shed light on the mysterious neutrino, potentially proving that matter and antimatter can be one and the same particle.
