Experiments in Neutrinos & Dark Matter
The Maruyama group is exploring several topics in nuclear and particle astrophysics. The experiments range from studying properties of neutrinos to a search for dark matter. We are searching for annual modulation signature from dark matter with the DM-Ice experiment, currently running a 17 kg version at the South Pole, with a 250 kg experiment currently being designed. We are also using the IceCube Neutrino Observatory to study fundamental properties of neutrinos using nearby supernovae. With CUORE, we are looking for a process called neutrinoless double beta decay. If such a process is observed, it would mean that neutrinos are their own antiparticles, and may hold the clue to why we live in a Universe of matter, and not antimatter. The experiment is located in the Gran Sasso National Underground Laboratory in Italy.
