Research summary

Neutrinos are the most abundant known massive particles in the universe—yet most of their fundamental properties, such as their mass, remain uncharted. One of the most pressing questions about neutrinos is how many different kinds there may be.

Dr. Thomas Brunner, Canada Research Chair in Astropastide Physics: Hunting for Weak decays without neutrinos, is investigating the nature of neutrinos. He is trying to determine whether neutrinos and anti-neutrinos are, in fact, identical particles. To do this, he and his research team must go deep underground in the southeastern New Mexico nuclear corridor with their nEXO detector. (nEXO stands for “next EXO,” a collaborative project to search for neutrinoless double-beta decay.) They are developing ultra-sensitive, low-background detection techniques through nEXO to shed light on the nature of neutrinos.
