New limits on di-nucleons decay into invisible channels
Abstract
Data of the radiochemical experiment (E.L. Fireman, 1978) with 1.7 t of KC2H3O2, accumulated deep underground during \simeq1 yr, were reanalyzed to set limits on di-nucleons (nn and np) decays into invisible channels (disappearance, decay into neutrinos, etc.). The obtained lifetime bounds τnp>2.1• 1025 yr and τnn>4.2• 1025 yr (at 90% C.L.) are better (or competitive) than those established in the recent experiments.
