  "abstract": "We study cubic interactions of $\\mathcal N=2$ massless integer-spin gauge supermultiplets in harmonic superspace. We construct the complete class of abelian $(\\mathbf{s},\\mathbf{s_1},\\mathbf{s_2})$ cubic vertices with the minimal number of space-time derivatives. Such vertices exist only for $\\mathbf{s}\\geq \\mathbf{s_1}+\\mathbf{s_2}$ and universally take the form of the gauge prepotential coupled to the conserved higher-spin supercurrent. For~$\\mathbf{s_1}\\neq\\mathbf{s_2}$, we find the novel complex principal supercurrent, whose real and imaginary parts generate the parity-invariant and the parity-breaking interactions, respectively. The supercurrents are constructed from gauge-invariant $\\mathcal N=2$ higher-spin Weyl supertensors associated with the spin-$\\mathbf{s_1}$ and spin-$\\mathbf{s_2}$ gauge multiplets. These supertensors are defined in terms of unconstrained higher-spin analytic prepotentials. We also derive the complete set of conserved component higher-spin currents associated with the $(s,s_1,s_2)$ vertices, including both traceless currents and currents with the non-vanishing trace.",
