Self-dual Yang-Mills multiplet in three dimensions coupled to supergravity

Le résumé fourni par la source

We couple a recently established $N=1$ globally supersymmetric self-dual Yang-Mills multiplet in three dimensions to supergravity. This becomes possible due to our previous result on globally supersymmetric formulation based on a compensator multiplet. We further couple the self-dual vector to a supersymmetric $\ensuremath{\sigma}$-model on the coset $SO(8,n)/SO(8)\ifmmode\times\else\texttimes\fi{}SO(n)$ via minimal couplings for an arbitrary gauged subgroup ${H}_{0}\ensuremath{\subset}SO(8)\ifmmode\times\else\texttimes\fi{}SO(n)$. A corresponding superspace formulation is also presented.
