Topological couplings in higher derivative extensions of supersymmetric three-form gauge theories

arXiv:1810.12678 · doi:10.1007/JHEP05(2019)102

Abstract

We consider a topological coupling between a pseudo-scalar field and a 3-form gauge field in supersymmetric higher derivative 3-form gauge theories in four spacetime dimensions. We show that ghost/tachyon-free higher derivative Lagrangians with the topological coupling can generate various potentials for the pseudo-scalar field by solving the equation of motion for the 3-form gauge field. We give two examples of higher derivative Lagrangians and the corresponding potentials: one is a quartic order term of the field strength and the other is the term which can generate a cosine-type potential of the pseudo-scalar field.
