Description

After a short introduction on the low background liquid xenon DAMA set-up (DAMA/LXe) and its main previous results, we discuss the search for the nucleon, di-nucleon and tri-nucleon decays into invisible channels (disappearance or decay to neutrinos, Majorons, etc.) in the 136Xe isotope. The obtained limits (90% C.L.) on the lifetimes are: τn>3.3.1023 yr, τp>4.5.1023 yr, τnp>3.2.1023 yr, τpp>1.9.1024 yr, τnnp>1.4. 1022 yr, τnpp>2.7.1022 yr and τppp>3.6.1022 yr. In particular, the tri-nucleon decay into invisible channels is investigated here for the first time. (orig.)
