Event Details

In the first part I will discuss cubic interactions of various 4D, N=1 matter supermultiplets with higher spin supermultiplets via Noether’s procedure. A ‘higher spin’ extension of superdiffeomorphism will be presented and it will guide the construction of higher spin supercurrents that generate the cubic interactions. In the second part I will consider cubic interactions of 4D, N=1 higher spin supermultiplets by constructing gauge invariant supercurrents. A special class of these supercurrents provide the supersymmetric and higher spin extension of the Bel-Robinson tensor known from GR.
