Spin-Statistics Violations in Superstring Theory

TL;DR

This paper explores potential observable violations of the spin-statistics theorem predicted by superstring theory, through specific models involving string interactions and noncommutative geometry, suggesting experimental tests for these phenomena.

Contribution

It introduces novel mechanisms within superstring theory that could lead to observable spin-statistics violations, providing a basis for experimental verification.

Findings

Heterotic worldsheet linkings can produce measurable statistical phases.

Noncommutative geometry in braneworld models modifies field (anti)commutators.

Proposes experimental tests for superstring-induced spin-statistics violations.

Abstract

I describe how superstring theory may violate spin-statistics in an experimentally observable manner. Reviewing the basics of superstring interactions and how to utilize these to produce a statistical phase, I then apply these ideas to two specific examples. The first is the case of heterotic worldsheet linkings, whereby one small closed string momentarily enlarges sufficiently to pass over another, producing such a statistical phase. The second is the braneworld model with noncommutative geometry, whereby matter composed of open strings may couple to a background in which spacetime coordinates do not commute, modifying the field (anti)commutator algebra. I conclude with ways to sharpen and experimentally test these exciting avenues to possibly verify superstring theory.
