Abstract
The Majorana Demonstrator is an ultra-low-background experiment searching for neutrinoless double-beta decay in . The heavily shielded array of germanium detectors, placed nearly a mile underground at the Sanford Underground Research Facility in Lead, South Dakota, also allows searches for new exotic physics. We present the first limits for trinucleon decay-specific modes and invisible decay modes for Ge isotopes. We find a half-life limit of for the decay and for the decay . The half-life limit for the invisible triproton decay mode of was found to be .
