Abstract

<p>Neutrinos are fermions that make up the Standard Model of elementary particles. Neutrinos, which have no electric charge, may be Majorana particles capable of converting between particles and antiparticles. In order to prove the Majorana nature of neutrinos, it is necessary to observe an extremely rare phenomenon called neutrino-less double beta decay. We have searched for double beta decays of 48Ca with the CANDLES experiment using a CaF2 scintillator. This paper describes the background physics and the main focus on the high sensitivity of the experimental setup, which the author has played a central role in.</p>
