Main results and perspectives on other rare processes with DAMA experiments

Abstract

Development of low radioactive technique allows to investigate many other rare nuclear and subnuclear processes: double [Formula: see text] decay, rare [Formula: see text] and [Formula: see text] decays, and to search for hypothetical particles and processes like axions, charge nonconserving decays, the nucleon, di-nucleon and tri-nucleon decays into invisible channels, to test the Pauli principle. Here, we present results of the rare processes searches and development of instrumentation for low counting experiments.
