Condensate Structure of D-particle Induced Flavour Vacuum

TL;DR

This paper explores how non-perturbative string effects induce four-fermion interactions that form condensates, leading to a flavor vacuum structure in models with large extra dimensions.

Contribution

It introduces a novel connection between string-induced four-fermion interactions and flavor vacuum condensates in large extra dimension models.

Findings

Four-fermion interactions can lead to flavor vacuum condensates.

Stringy non-perturbative effects influence flavor structure.

Condensate formation depends on specific model conditions.

Abstract

It is argued that four Fermi interactions induced by non-perturbative effects due to scattering of stringy matter from D-particles, D-instantons and more generally bulk gauge fields in models with large extra dimensions have in specific situations condensate structure described by flavour vacua.
