Supersymmetric Born-Infeld from the D9-brane

Using the superembedding approach, the full supersymmetric effective field theory of the D9-brane, super Born-Infeld theory, is fixed by the so-called F-constraint. The odd-odd components of the theory's super field strength, f(alphabeta), are implied by this constraint. Given f(alphabeta), the super Bianchi identities imply the theory's equations of motion. We calculate f(alphabeta) up to order 5 in fields, corresponding to order 6 in fields in the Lagrangian.
