discussion led by Panteleimon Tziveloglou

Abstract: We use constrained superfields to derive the coupling of an N = 2 hypermultiplet with the DBI theory of 1 linear + 1 nonlinear global supersymmetry. This is a field theory construction of the Lagrangian that describes the interaction between Maxwell brane fields and the universal hypermultiplet, in the limit of decoupled gravity. Both the dilaton dressed DBI and the CS terms - 'including' the 4-form - are obtained. The theory enjoys some interesting features, including a super-higgs mechanism without gravity.
