Narrow Results

DAMA/NaI and DAMA/LIBRA data have allowed the study of several rare processes. In this paper, the results obtained for internal pair production in ${}^{241}$Am $\alpha$ decay, charge not conserving electron capture in ${}^{127}$I and possible processes violating the Pauli Exclusion Principle are briefly discussed.

The application of very low background techniques is fundamental in deep underground experiments dedicated to the investigation of rare processes. In this paper, the case of NaI(Tl) detectors is discussed mainly considering their crucial role for direct Dark Matter (DM) investigation. In particular, the DAMA/LIBRA apparatus, as a result of a long-standing activity focused on the optimization of NaI(Tl) detectors, is underlined.

Borexino was designed to measure solar neutrinos in the MeV or sub-MeV energy range. The unprecedented radiopurity of the detector has allowed the detection of geo-neutrinos and the determination of competitive limits on the rate of rare or forbidden processes. In this paper, we review the basic principle of neutrinos and antineutrinos detection in Borexino and we describe the results of the geo-neutrinos measurements and their implications. Then we summarize the search for Borexino events correlated with gamma ray bursts and for axion induced signals, and the limits achieved on Pauli forbidden transitions and on the electron charge conservation.

This session has been dedicated to several topics of Dark Matter (DM) and Rare Processes (RP) field. Some talks have review character while others present some specific experimental results and developments. Mainly the contributions refer to Dark Matter (DM) topics while the last contribution discusses a specific rare process…
