Aa. Deriglazov et Dm. Gitman, EXAMPLES OF D=11 S-SUPERSYMMETRIC ACTIONS FOR POINT-LIKE DYNAMICAL-SYSTEMS, Modern physics letters A, 13(32), 1998, pp. 2559-2570
A nonstandard super extensions of the Poincare algebra (S-algebra(1,2)
), which seems to be relevant for construction of various D = 11 model
s, are studied. We present two examples of actions for point-like dyna
mical systems, which are invariant under off-shell closed realization
of the S-algebra as well as under local fermionic kappa-symmetry. On t
his ground, an explicit form of the S-algebra is advocated.
