摘要
En 中文
We have constructed conserved N = 2 higher-spin supercurrents for an arbitrary integer spin through unconstrained superfield formulation of 4D, N = 2 massless higher-spin theories in the harmonic superspace. The obtained supercurrents are gauge-invariant and determine consistent cubic interactions in the gauge superfield x supercurrent form for massless spin s(1) and two massless spin s(2) N = 2 supermultiplets. Such interactions N = 2 supercurrents exist only for s(1) >= 2s(2). These supercurrents are the N = 2 supersymmetric extension Berends-Burgers-van Dam higher-spin currents and generalize the linearized Bel-Robinson tensor. The relevant N = 2 supercurrents can be considered as the descendants of the N = 2 principle supercurrent, which has simple universal structure. An important feature of our outcomes is that, ultimately, all N = 2 supercurrents built from the N = 2 superfield strengths, which are constructed from the unconstrained analytical higher-spin prepotentials.
