2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/189472We construct a new two-dimensional N=8 supersymmetric mechanics with nonlinear chiral supermultiplet. Being intrinsically nonlinear this multiplet describes 2 physical bosonic and 8 fermionic degrees of freedom. We construct the most general superfield action of the sigma-model type and propose its simplest extension by a Fayet-Iliopoulos term. The most interesting property of the constructed system is a new type of geometry in the bosonic subsector, which is different from the special Kahler one characterizing the case of the linear chiral N=8 supermultiplet.9 pages, no figures, minor correctionsHigh Energy Physics - TheoryN=8 Nonlinear Supersymmetric Mechanicstext
