Quantum Gravity, Flavour Vacua and Supersymmetry

TL;DR

This paper reviews a non-perturbative mechanism for breaking supersymmetry through flavour mixing influenced by quantum gravity effects, specifically in string theory backgrounds that violate Lorentz and CPT symmetries.

Contribution

It introduces a novel approach to supersymmetry breaking via flavour mixing caused by interactions with quantum gravity space-time foam, emphasizing non-perturbative effects.

Findings

Flavour mixing can be dynamically induced by quantum gravity interactions.

Supersymmetry breaking arises from Lorentz and CPT violation in stringy backgrounds.

The model suggests a link between quantum gravity and particle flavor phenomena.

Abstract

I review a novel and non-perturbative way of breaking Supersymmetry in the flavour sector of electrically neutral particles, as a result of flavour mixing in the presence of stringy quantum gravity space-time foam backgrounds that violate Lorentz and CPT symmetries. In these models, part of the mixing may itself be induced dynamically by the interactions of the flavoured particles with the space-time foam.
