Generalized Supersymmetries and Composite Structure in M-Theory
J. Lukierski
Abstract
We describe generalized D=11 Poincaré and conformal supersymmetries. The corresponding generalization of twistor and supertwistor framework is outlined with OSp(1|64) superspinors describing BPS preons. The k32 BPS states as composed out of n=32 - k preons are introduced, and basic ideas concerning BPS preon dynamics is presented. The lecture is based on results obtained by J.A. de Azcarraga, I. Bandos, J.M. Izquierdo and the author1.
