LiLAND - LIthium Electron Antineutrino Source at KamLAND

ABSTRACT

Standard neutrinos come in three flavors, each of which is associated with a particular charged lepton: electron, muon or tau.

While the three-flavor neutrino standard model seems to work fine to explain the data from solar, atmospheric, accelerator and

reactor experiments, hint of the fourth flavor of neutrino, coming from LSND and MiniBooNE experiments is worth to pursue.

These results may be interpreted in the context of mixing involving one or more sterile neutrinos, a possibility which has excited

the physics community. LiLAND experiment proposal is based on a high intensity antineutrino source, originating from the β^- decay

of ⁸Li, coupled to KamLAND, a massive scintillator-based detector. We propose using DT neutron generator as a source of

neutrons required for the production of ⁸Li, and resulting antineutrinos. Possibility of intensive antineutrino source close to KamLAND

would increase detection statistics and allow to distinguish between models with one or two sterile neutrino flavors.
