Conformal Invariance, N-extended Supersymmetry and Massless Spinning Particles in Anti-de Sitter Space
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.Comment: 13 pages, LaTe
