Plutonium decay experiment seeks sterile neutrinos as dark matter candidate
Researchers at Lawrence Livermore National Laboratory are using plutonium-241 beta decays to search for sterile neutrinos, a hypothetical particle that could constitute warm dark matter. The Magneto-ν experiment precisely measures the decay products to infer the energy of the escaping antineutrino. Their initial results have been published in Physical Review C.
