Some recent DAMA/NaI results on
The electric charge conservation is a fundamental law of quantum electrodynamics;
nevertheless, because there is the possibility that it may be broken in future unified gauge
theories, many efforts have been devoted to test it with different procedures by various
In particular, by using the ~100 kg NaI(Tl), we have achieved the new results summarized in the following:
e- → 3ν, majoron + ν or anything invisible:
(up to two orders of magnitude higher than the ones previously available).
Stringent restrictions on the relative strengths of the charge non-conserving (CNC) processes are derived (90% C.L.):
