Nonlinear (3, 4, 1) Multiplet of N=4, d=1 Supersymmetry as a Semidynamical Spin Multiplet / E.Ivanov, S.Sidorov // Physical Review D [Electronic resource]. – 2024. – Vol. 109, No. 8. – P. 086001. – URL: https://doi.org/10.1103/PhysRevD.109.086001. – Bibliogr.: 28.

We consider a new type of N=4, d=1 semidynamical multiplet based on the nonlinear version of the mirror multiplet (3, 4, 1), with the triplet of bosonic physical fields parametrizing a three-dimensional sphere S*3 of the radius R. The limit R→∞ amounts to the contraction S*3→R*3 and leads to the linear mirror multiplet (3, 4, 1). Spin degrees of freedom described by a Wess-Zumino action specify a two-dimensional surface embedded in the sphere S*3. A pair of the examples considered correspond to the round and squashed “fuzzy” 2-spheres. We couple the squashed 2-sphere model to the dynamical mirror multiplet (2, 4, 2). A notable feature of this coupling is the dependence of the squashing parameter on the bosonic fields z, ¯z of the chiral multiplet.
