Nonaccelerator experiments on the search for rare processes with low-background detectors

摘要

The status of the search for rare processes with low-background detectors is reviewed. The discussed experimental results include searches for the neutrino magnetic moment and neutrino decays, the violation of electric and baryon charge conservation, the violation of the Pauli exclusion principle, and new heavy-mass eigenstates of the neutrino. New bounds on the probability of these processes, obtained with a prototype of the Borexino detector, are presented.
