TL;DR
This paper addresses the issue of extra fermionic degrees of freedom in chiral gauge theories derived from Connes Noncommutative Geometry by proposing a mechanism to give these mirror states high mass, ensuring they do not affect low energy physics.
Contribution
It introduces a novel mechanism to decouple mirror fermions in noncommutative geometry-based chiral gauge theories.
Findings
Mirror fermions can be given high mass to decouple from low energy physics
The proposed mechanism effectively suppresses mirror states in the model
Enhances the viability of noncommutative geometry approaches to particle physics
Abstract
In a recent paper we pointed out the presence of extra fermionic degrees of freedom in a chiral gauge theory based on Connes Noncommutative Geometry. Here we propose a mechanism which provides a high mass to these mirror states, so that they decouple from low energy physics.
