Abstract Constructing a consistent four-dimensional Lagrangian for charged massive higher-spin fields propagating in an electromagnetic background is an open problem. In 1989, Argyres and Nappi used bosonic open string field theory to construct a Lagrangian for charged massive spin-2 fields in a constant electromagnetic background. In this paper, we use the four-dimensional hybrid formalism for open superstring field theory to construct a supersymmetric Lagrangian for charged massive spin-2…

Supersymmetric Born-Infeld from the pure spinor formalism of the open superstring
Classical BRST invariance in the pure spinor formalism for the open superstring is shown to imply the supersymmetric Born-Infeld equations of motion for the background fields. These equations are
Lagrangian formulation for arbitrary spin. I. The boson case
An explicit form is obtained for the Lagrangian of an arbitrary-spin boson field. This is achieved by introducing auxiliary field variables which are required to vanish in the free-field limit. For

Spin-1 effective actions from open strings
Abstract Interacting equations of motion for spin-1 fields (both neutral and charged) in an electromagnetic background are derived from the open bosonic string by requiring BRST invariance. These

Broken Supersymmetry and Supergravity
We consider the supersymmetric Higgs effect, in which a spin-\textonehalf{} Goldstone fermion is transformed away by a redefinition of the supergravity fields and the spin-$\frac{3}{2}$ gauge field
