Hidden Superconformal Symmetry in M Theory

TL;DR

This paper explores the hidden superconformal symmetry in M theory, proposing that Osp(1/64) is a fundamental symmetry, and derives related bosonic sectors and effective actions through non-linear realisations.

Contribution

It introduces the idea that Osp(1/64) underpins M theory's symmetry structure and derives key sectors as non-linear realisations, offering new insights into M theory's symmetry framework.

Findings

Osp(1/64) is proposed as a symmetry of M theory

Bosonic sectors of supergravity are derived as non-linear realisations

Effective action of the closed bosonic string is obtained as a non-linear realisation

Abstract

The bosonic sectors of the eleven dimensional and IIA supergravity theories are derived as non-linear realisations. The underlying group includes the conformal group, the general linear group and as well as automorphisms of the supersymmetry algebra. We discuss the supersymmetric extension and argue that Osp(1/64) is a symmetry of M theory. We also derive the effective action of the closed bosonic string as a non-linear realisation.
