A New Type of Massive Spin-one Boson: and Its Relation with Maxwell Equations

The text book understanding of quantum field theory states that a fermion and its associated antifermion have opposite relative intrinsic parity; and that a boson and its associated antiboson carry same relative intrinsic parity. No particles that do not fall within this understanding, coupled with the fact that no quantum field theory was known to exist that contradicted this canonical wisdom, has led to almost complete neglect of the fact that long ago Wigner [1] 1 argued that space-time symmetries, and that these manifest in quantum constructs as projective representations, do allow for theories where a fermion and its associated antifermion have same relative intrinsic parity; and that a boson and its associated antiboson carry opposite relative intrinsic parity. The only scholarly footnote to the canonical wisdom in the widely read literature, see for example Refs. [7], that refers to Wigner’s observations is Appendix C of Weinberg’s latest monograph on the quantum theory of fields [8]. Recently [2], purely by accident (see Acknowledgements), in an attempt to understand an old work of Weinberg [9] and to investigate the possible
