Weyl and Majorana for neutral particles

Abstract

AbstractWe compare various formalisms for neutral particles. It is found that they contain unexplained contradictions. Next, we investigate the spin‐1/2 and spin‐1 cases in different bases. Next, we look for relations with the Majorana‐like field operator. We show explicit incompatibility of the Majorana ansatzen with the Dirac‐like field operators in both the original Majorana theory and its generalizations.
