Boson-Fermion Confusion: The String Path To Supersymmetry

TL;DR

This paper explores the origins of supersymmetry in string theory, emphasizing the role of boson-fermion confusion in superstring models and discussing the subtle boson-fermion relationship in eleven dimensions involving the exceptional group F4.

Contribution

It highlights the significance of boson-fermion confusion in superstring theories and proposes a potential link to the exceptional group F4 in eleven-dimensional frameworks.

Findings

Boson-fermion confusion is crucial in 9+1 dimensional superstring theories.

The relationship between bosons and fermions in eleven dimensions may involve the exceptional group F4.

Reminiscences connect string origins to supersymmetry development.

Abstract

Reminiscences on the String origins of Supersymmetry are followed by a discussion of the importance of confusing bosons with fermions in building superstring theories in 9+1 dimensions. In eleven dimensions, the kinship between bosons and fermions is more subtle, and may involve the exceptional group $F_4$.
