Non-linear (3, 4, 1) multiplet of $\mathcal{N}=4$, $d=1$ supersymmetry as a semi-dynamical spin multiplet

Evgeny Ivanov, Stepan Sidorov

We consider a new type of $\mathcal{N}=4$, $d=1$ semi-dynamical multiplet based on the non-linear version of the mirror multiplet $(3,4,1)$, with the triplet of bosonic physic…
