• Popis: We give an explicit superspace construction of higher spin conserved supercurrents built out of 4D, N = 1 massless supermultiplets of arbitrary spin. These supercurrents are gauge invariant and generate a large class of cubic interactions between a massless supermultiplet with superspin Y-1= s(1) + 1/2 and two massless supermultiplets of arbitrary superspin Y-2. These interactions are possible only for s(1 )>= 2Y(2). At the equality, the supercurrent acquires its simplest form and defines the supersymmetric, higher spin extension of the linearized Bel-Robinson tensor.
