Structure of N=2 Superfield Higher-Spin Abelian Cubic Interactions / N.Zaigraev. – Text : electronic // Journal of High Energy Physics. – 2026. – No. 9. – P. 181. – URL: https://doi.org/10.1007/JHEP09(2026)181. – Bibliogr.: 96.

In this article we study the structure of the N = 2 abelian higher-spin cubic (s&sub(1), s&sub(2), s&sub(2) vertices and the corresponding N = 2 higher-spin supercurrents, introduced in arXiv:2408.00668. These interactions are possible only for s&sub(1) ≥ 2s&sub(2). Conserved supercurrents are constructed as descendants of the principal supercurrent, which is uniquely characterized by simple differential conditions and admits an explicit representation in terms of N = 2 higher-spin super-Weyl tensors. We derive the analytic form of the abelian vertices and identify the corresponding analytic higher-spin N = 2 supercurrents. We show that the vertex structure is fully determined by the analytic supercurrents J^-*+*+&sub(*a(s-1)*a(s-1)), J*+&sub(*a(s-1)*a(s-2)), and J^-*+&sub(*a)(s-2)*a(s-1)). The analytic form of the vertices provides a simple framework for analyzing their component structure. As an example, we explore the component content of such interactions on the Bel-Robinson diagonal. Using the superfield inverse Noether procedure, we study higher-spin gauge transformations for the N = 2 vector multiplet associated with the (s, 1, 1) interaction. In the rigid limit, for odd s these transformations reduce to the N = 2 superspace generalization of zilch-type higher-spin symmetries.
