Generalized Supersymmetries and Composite Structure in M-theory
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 k 32 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 Azcarra...
متن کاملM - theory PP - Waves , Penrose Limits and Supernumerary Supersymmetries
We study supersymmetric pp-waves in M-theory, their dimensional reduction to D0-branes or pp-waves in type IIA, and their T-dualisation to solutions in the type IIB theory. The general class of pp-waves that we consider encompass the Penrose limits of AdS p × S q, but includes also many other examples that can again lead to exactly-solvable massive strings, but which do not arise from Penrose l...
متن کاملComposite Supersymmetries in low - dimensional systems
Starting from a N = 1 scalar supermultiplet in 2+1 dimensions, we demonstrate explicitly the appearance of induced N = 1 vector and scalar supermultiplets of composite operators made out of the fundamental supersymmetric constituents. We discuss an extension to a N = 2 super-algebra with central extension, due to the existence of topological currents in 2+1 dimensions. As a specific model we co...
متن کاملGeneralized Holonomy of M-theory Vacua
The number of M-theory vacuum supersymmetries, 0 ≤ n ≤ 32, is given by the number of singlets appearing in the decomposition of the 32 of SL(32,R) under H ⊂ SL(32,R) where H is the holonomy group of the generalized connection which incorporates non-vanishing 4-form. Here we compute this generalized holonomy for the n = 16 examples of the M2-brane, M5-brane, M-wave, M-monopole, for a variety of ...
متن کاملHidden Spacetime Symmetries and Generalized Holonomy in M - theory
In M-theory vacua with vanishing 4-form F(4), one can invoke the ordinary Riemannian holonomy H ⊂ SO(1, 10) to account for unbroken supersymmetries n = 1, 2, 3, 4, 6, 8, 16, 32. However, the generalized holonomy conjecture, valid for non-zero F(4), can account for more exotic fractions of supersymmetry, in particular 16 < n < 32. The conjectured holonomies are given by H ⊂ G where G are the gen...
