Generalized Supersymmetries and Composite Structure in M-Theory

TL;DR

This paper explores generalized supersymmetries in eleven-dimensional M-theory, introduces BPS preons as fundamental building blocks, and discusses their potential composite structure and dynamics within an extended twistor framework.

Contribution

It presents a novel extension of supersymmetry and twistor formalisms in M-theory, introducing BPS preons and their role in constructing BPS states.

Findings

Generalized D=11 supersymmetries described.

BPS preons as fundamental constituents introduced.

Framework for BPS state composition outlined.

Abstract

We describe generalized D=11 Poincar\'{e} and conformal supersymmetries. The corresponding generalization of twistor and supertwistor framework is outlined with $OSp(1|64)$ superspinors describing BPS preons. The $\frac{k}{32}$ 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 Azcarraga, I. Bandos, J.M. Izquierdo and the author$^1$.
