N=8 Supersymmetric Mechanics with Spin Variables from Indecomposable Multiplets / E.Ivanov, S.Sidorov. – Text : electronic // Physical Review D. – 2026. – Vol. 113, No. 6. – P. 066001. – URL: https://doi.org/10.1103/tcwy-y4tg. – Bibliogr.: 24.

We define two new indecomposable (not fully reducible) 𝒩 =8, 𝑑 =1 off-shell multiplets and consider the corresponding models of 𝒩 =8 supersymmetric mechanics with spin variables. Each multiplet is described off shell by a scalar superfield which is a nonlinear deformation of the standard scalar superfield 𝑋 carrying the 𝑑 =1 multiplet (𝟏,𝟖,𝟕). Deformed systems involve, as invariant subsets, two different off-shell versions of the irreducible multiplet (𝟖,𝟖,𝟎). For both systems we present the manifestly 𝒩 =8 supersymmetric superfield constraints, as well as the component off- and on-shell invariant actions, which for one version exactly match those given in arXiv:2402.00539. The two models differ off shell, but prove to be equivalent to each other on shell, with the spin variables sitting in the adjoint representation of the maximal 𝑅-symmetry group SO⁡(8).
