1. The solar neutrino experiments include Homestake, Kamiokande, GALLEX, SAGE, and SuperKamiokande. The atmospheric neutrino data is from Kamiokande, IMB, Soudan, SuperKamiokande with highest statistics, and MACRO. The LSND experiment also reports evidence for neutrino oscillations, although this has not been confirmed (or completely excluded) by the KARMEN experiment. The K2K and SNO experiments are in progress. Recent experimental reviews include
2. Double-beta decay and a massive Majorana neutrino
3. On muonic double-βdecays of pseudoscalar mesons
