Spacelike deformations: Higher-helicity fields from scalar fields

Mathematical Physics 2020-09-03 v2 High Energy Physics - Theory math.MP

Abstract

In contrast to Hamiltonian perturbation theory which changes the time evolution, "spacelike deformations" proceed by changing the translations (momentum operators). The free Maxwell theory is only the first member of an infinite family of spacelike deformations of the complex massless Klein-Gordon quantum field into fields of higher helicity. A similar but simpler instance of spacelike deformation allows to increase the mass of scalar fields.
