Restricting the form of interaction Hamiltonians for systems of fermions, antifermions, and bosons Asman, Charles Phillip


In this thesis, we define two general interaction Hamiltonians, one for describing systems of interacting nucleons, antinucleons and pions, the other for describing systems of interacting electrons positrons and photons. We then demand that the Hamiltonians should each remain invariant under the action of a certain class of transformations. By imposing this requirement, the allowed forms of the Hamiltonians are greatly restricted.
