MOG without anomaly

TL;DR

This paper derives an anomaly-free version of Moffat's Modified Gravity (MOG) by extending the Horava-Witten mechanism to fourteen dimensions and proposes an extended MOG including fermionic fields.

Contribution

It introduces a novel anomaly-free formulation of MOG through higher-dimensional generalization and extends the theory to incorporate fermionic fields.

Findings

MOG can be made anomaly-free in fourteen dimensions.

The extended MOG includes fermionic fields.

The approach generalizes the Horava-Witten mechanism.

Abstract

We obtain the action of Moffat's Modified Gravity, (MOG), a scalar-tensor-vector theory of gravitation, by generalizing the Horava-Witten mechanism to fourteen dimensions. We show that the resulting theory is anomaly-free. We propose an extended version of MOG that includes fermionic fields.
