N=8 Invariant Interaction of Dynamical and Semidynamical N=4 Multiplet / S.Fedoruk, E.Ivanov // Physical Review D [Electronic resource]. – 2024. – Vol. 109, No. 8. – P. 085007. – URL: https://doi.org/10.1103/PhysRevD.109.085007. – Bibliogr.: 31.

We present a new model of N = 8 mechanics with semidynamic supermultiplets. The model is constructed as an interaction of N= 4 supermultiplets which carry an implicit N = 4 supersymmetry. The initial field content consists of three dynamical (1; 4; 3) multiplets: one bosonic and two fermionic. To ensure implicit N = 4 supersymmetry, we introduce the superfields describing three semidynamical (4; 4; 0) multiplets: one fermionic and two bosonic. To avoid the second-order Lagrangian for fermions from the fermionic (1; 4; 3) multiplets, we convert their velocities into new auxiliary fields. After conversion, these multiplets turn into semidynamical mirror (4; 4; 0) multiplets without noncanonical terms in the N = 8 Lagrangian at the component level. The final N = 8 multiplet content is (1; 8; 7) ⊕ (8; 8; 0). As a first step to the ultimate N = 4 superfield formulation of the model, we recall a natural description of the standard and mirror (4; 4; 0) multiplets in the framework of N = 4; d = 1 biharmonic superspace.
