N = 2 Higher-Spin Supercurrents / N.Zaigraev // Physics Letters B [Electronic resource]. – 2024. – Vol. 858. – P. 139056. – URL: https://doi.org/10.1016/j.physletb.2024.139056. – Bibliogr.: 28.

We have constructed conserved N = 2 higher-spin supercurrents for an arbitrary integer spin through the 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 × supercurrent form for massless spin 𝐬𝟏 and two massless spin s&sub(2) N = 2 supermultiplets. Such interactions and N = 2 supercurrents exist only for s&sub(1) *} 2s&sub(2). These supercurrents are the N = 2 supersymmetric extension of 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 a simple universal structure. An important feature of our outcomes is that, ultimately, all N = 2 supercurrents are built from the N = 2 superfield strengths, which are constructed from the unconstrained analytical higher-spin prepotentials.
