found: The MAJORANA Neutrinoless Double-beta Decay Experiment website, via University of Washington Center for Experimental Nuclear Physics and Astrophysics website, June 11, 2020(MAJORANA is an experiment to search for neutrinoless double-beta decay; If this decay occurs, the neutrino is its own antiparticle, or a Majorana particle. The observation of neutrinoless double-beta decay would determine whether the neutrino is a Majorana particle and provide information on the absolute scale of neutrino mass. If the neutrino is a Majorana particle, neutrinos could provide a mechanism for the matter/anti-matter imbalance of our universe)
found: A dictionary of physics, 2019(Majorana fermion: A fermion that is its own antiparticle (as opposed to a Dirac fermion, where this is not the case). The idea of a Majorana fermion was proposed by Ettore Majorana (1906-?) in 1937, shortly before his mysterious disappearance. It is not known whether neutrinos are Majorana or Dirac fermions. It is natural for many of the fermions in supersymmetry to be Majorana fermions. Majorana fermions can occur as quasiparticles in the theory of condensed-matter physics)
found: Buuck, M. A radiogenic background model for the MAJORANA DEMONSTRATOR, 2019:p. x (Majorana fermion: A Majorana fermion is a particle with half-integer spin and no electric charge that obeys Majorana statistics. Among the known fundamental particles, neutrinos are the only candidates to be Majorana fermions, as all other fundamental fermions carry nonzero electric charge. Recently, evidence for multi-particle systems obeying Majorana statistics has been discovered in the field of condensed matter physics and was the first observance of Majorana particles in nature)
found: Wikipedia, June 11, 2020(A Majorana fermion, also referred to as a Majorana particle, is a fermion that is its own antiparticle. They were hypothesized by Ettore Majorana in 1937. The term is sometimes used in opposition to a Dirac fermion, which describes fermions that are not their own antiparticles)

Are neutrinos their own antiparticles?, 2009, via arXiv website, viewed June 11, 2020:p. 3 (the observation of double-beta decay would imply the existence of a non-vanishing amplitude that is equivalent to a Majorana mass term. Consequently, this observation would also imply that neutrinos are Majorana particles)
