Neutrinoless Double Beta Decay Experiment: AMoRE(Advanced Mo-based Rare-process Experiment)

The recent discovery of neutrino oscillations clearly indicates that neutrinos do have mass, which is compelling evidence of physics beyond the standard model of particle physics. However, while those observations provide information about the differences in the neutrino masses, they do not provide a direct measurement of the absolute mass scale and they leave unanswered questions about the properties of neutrinos. To answer to those questions, the AMoRE (Advanced Mo-based Rare-process Experiment) will conduct one of the most sensitive searches for “neutrinoless double beta decay” in which only two electrons emerge from nuclear-beta decays, by using CaMoO4 crystal scintillators at cryogenic temperature. If such decays were observed, it would be a clear signal that neutrinos have a different mass structure than other elementary particles and would provide a measurement of the absolute neutrino mass scale and give a clue for explaining the large baryon asymmetry in our universe, called the leptogenesis theory.
