Intersecting Branes in M-Theory and Chiral Matter in Four Dimensions

TL;DR

This paper constructs two four-dimensional M-theory brane-world models with anomaly-free chiral spectra, connected by a five-dimensional bulk, using a specific global quotient to ensure local consistency and chiral matter emergence.

Contribution

It explicitly derives a pair of M-theory brane-world models with anomaly-free chiral spectra linked by a five-dimensional bulk, based on a specific global quotient.

Findings

Two consistent four-dimensional M-theory models with chiral matter.

Models are connected via a five-dimensional bulk.

Anomaly cancellation achieved through local consistency requirements.

Abstract

We explicitly derive a complementary pair of four-dimensional M-theory brane-world models, linked by a five-dimensional bulk, each of which has a unique anomaly-free chiral spectrum. This is done via resolution of local consistency requirements, in the context of the simplest global quotient T7/G with ten-dimensional fixed-planes, for which a chiral four-dimensional spectrum could arise.
