A prediction of string theory testable at low energies

TL;DR

This paper explores how superstring theory's low-energy limit predicts electron interference patterns that differ from traditional Dirac current predictions, suggesting potential experimental tests for string theory.

Contribution

It introduces a relativistic-covariant probabilistic interpretation of the superstring current, leading to novel low-energy predictions distinct from standard quantum mechanics.

Findings

Electron interference patterns differ from Dirac predictions under certain conditions.

Superstring current generalizes Klein-Gordon current in low-energy limit.

Potential experimental tests for superstring theory at accessible energies.

Abstract

Superstring theory involves a single unifying superstring current for bosons and fermions that in the low-energy limit generalizes the Klein-Gordon (not the Dirac) current. By adopting a relativistic-covariant probabilistic interpretation of the current, the low-energy limit implies electron interference patterns that, under certain conditions, differ from those predicted by the Dirac current.
