Stringy phenomenology with preon models

TL;DR

This paper compares topological supersymmetric preon models with heterotic string theory, suggesting that fundamental particles are more likely preons based on symmetry and phenomenological analysis.

Contribution

It introduces a comparative analysis between preon models and string theory, incorporating Pati's supergravity preon model and examining their implications for fundamental particles.

Findings

Preons are more likely fundamental particles than standard model particles.

Symmetry comparisons support preons as fundamental entities.

Preon phenomenology aligns with the idea of preons as basic building blocks.

Abstract

We compare, following Pati, global symmetries our topological supersymmetric preon model with the heterotic E_8 x E_8 string theory. We include Pati's supergravity based preon model in this work and compare the preon interactions of his model to ours. Based on preon-string symmetry comparison and preon phenomenological results we conclude that the fundamental particles are likely preons rather than standard model particles.
