Note on supersymmetric Dirac-Born-Infeld action with Fayet-Iliopoulos term

High Energy Physics - Theory 2020-06-24 v2

Abstract

We study the Dirac-Born-Infeld (DBI) action with one linear and one non-linear supersymmetry in the presence of a constant Fayet-Iliopoulos (FI) D-term added explicitly or through a deformation of supersymmetry transformations. The linear supersymmetry appears to be spontaneously broken since the D auxiliary field gets a non-vanishing vacuum expectation value and an extra term proportional to the FI parameter involving fermions emerges in the non-linear formulation of the action written recently. However in this note, we show that on-shell this action is equivalent to a standard supersymmetric DBI action without{\it without} FI term but with redefined tension, at least up to order of mass-dimension 12 effective interactions.
