Abstract

In this paper, we define a new spinor classification that encompasses the recently proposed spin-half bosons with mass dimension three-half (Ahluwalia D. V., EPL, 131 (2020) 41001). As will be shown, these particles, which are governed by a first-order equation and consequently provide a local theory, belong to a specific subclass of class-2 spinors within the bosonic classification, playing a similar role to that of Dirac spinors within the Lounesto classification. Such bosonic classification is shown to be closely connected with the usual fermionic Lounesto classification, and thus, evincing a symmetry between Dirac fermions and spin-half bosons.
