TL;DR
This paper proposes a new lattice method to eliminate fermion doublers in anomaly-free chiral gauge theories, ensuring gauge invariance without fine-tuning or noninvariant counterterms.
Contribution
It introduces a novel approach for removing fermion doublers in lattice chiral gauge theories that maintains gauge invariance and avoids fine-tuning.
Findings
The continuum limit remains gauge invariant.
No noninvariant counterterms are needed.
The method effectively removes fermion doublers.
Abstract
A method for removing fermion doublers in anomaly free chiral gauge theories on the lattice is proposed. It is proven that the resulting continuum theory is gauge invariant and does not require noninvariant counterterms of fine tuning of parameters.
