Abstract:
Starting with a manifestly conformal ( invariant) mechanics model in space and 2 time dimensions, we derive the action for a massless spinning particle in -dimensional anti-de Sitter space. The action obtained possesses both gauge -extended worldline supersymmetry and local invarince. Thus we improve the old statement by Howe et al. that the spinning particle model with extended worldline supersymmetry admits only flat space-time background for (spin greater one). The original -dimensional model is characterized by rather unusual property that the corresponding supersymmetry transformations do not commute with the conformal ones, in spite of the explicit invariance of the action.Note:
