# Mass generation by a Lorentz-invariant gas of spacetime defects

## TL;DR

This paper introduces a Lorentz-invariant spacetime defect model that influences field propagation, leading to mass generation for scalars and fermions without violating Lorentz symmetry.

## Contribution

It proposes a simple, Lorentz-invariant defect model that explains mass generation mechanisms in flat spacetime without Lorentz violation.

## Key findings

- Defects induce mass for scalars and fermions.
- Lorentz invariance is maintained at large scales.
- Spacetime defects affect field propagation.

## Abstract

We present a simple model of defects embedded in flat spacetime, where the model is designed to maintain Lorentz invariance over large length scales. Even without remnant Lorentz violation, there are still effects from these spacetime defects on the propagation of physical fields, notably mass generation for scalars and Dirac fermions.
