| Abstract: | Nucleon decay is by definition a baryon number violating process, and within the context of the Standard Model(SM) of particle physics is forbidden. Extensions of the SM, such as Grand Unification Theories (GUTs), commonly require baryon number violation and nucleon decay. The Kamioka Liquid scintillator Anti-Neutrino Detector (KamLAND) is used in a search for single neutron intra-nuclear disappearance that would produce holes in the s-shell energy level of 12C nuclei. Such holes could be created as a result of nucleon decay into “invisible” (inv) modes, e.g. n → 3 . The de-excitation of the corresponding daughter nucleus results in a sequence of space and time correlated events observable in the liquid scintillator detector. We report on a new limit for neutron disappearance: (n → inv) > 6.02 × 1029 years (90% CL). |
