Supersymmetry in open superstring field theory

Supersymmetry in open superstring field theory

Abstract We realize the 16 unbroken supersymmetries on a BPS D-brane as invariances of the action of the corresponding open superstring field theory. We work in the small Hilbert space approach, where a symmetry of the action translates into a symmetry of the associated cyclic A ∞ structure. We comp...
