Preprint Explores Axion Quality and Proton Stability in High-Energy Physics

A new theoretical physics preprint by Joe Davighi, Admir Greljo, and Xavier Ponce Díaz investigates 'Axion Quality' linked to exact proton stability. This research proposes a discrete Z9 gauge symmetry that could prevent proton decay, addressing fundamental aspects of high-energy physics. The findings are preliminary and have not yet undergone peer review.
