$\mathcal{N}=4$ supersymmetric multiparticle systems based on indecomposable multiplets

Sergey Fedoruk, Evgeny Ivanov, Stepan Sidorov

We construct new multiparticle models of $\mathcal{N}=4$ supersymmetric mechanics with spin degrees of freedom by employing nonlinear indecomposable supermultiplets ${\bf (1,4,3){\…
