A new study published in Physical Review D , titled "Extending the Bridge Connecting Chiral Lagrangians and QCD Gaussian Sum-Rules for Low-Energy Hadronic Physics," presents a notable step forward in understanding the strong nuclear force—the fundamental interaction that binds protons and neutrons within atomic nuclei and plays a vital role in the formation of matter.
Co-authored by Dr. Amir Fariborz, Professor of Physics at SUNY Polytechnic Institute, the study expands on a theoretical framework first introduced by Dr. Fariborz and colleagues in 2016. This framework builds a conceptual link between the observable world of hadrons—composite particles like protons, neutrons, and mesons—and their more fundamental quark-level structure.
The latest work advances this model by incorporating higher-order effects, which improve the precision of predictions and make it possible to explore more complex subatomic phenomena. These include scalar and pseudoscalar mesons that may involve hybrid quark-gluon configurations and even mix with glueballs, hypothetical particles made entirely of gluons.
This research falls within hadronic physics, a field that bridges nuclear and particle physics and seeks to unravel how the strong interaction gives rise to the hadrons found in nature. While quantum chromodynamics (QCD) reliably describes strong interactions at high energies, its behavior at lower energies remains a key theoretical challenge. Traditional perturbative techniques fail to provide accurate descriptions in this regime.
By extending the QCD framework and aligning it with experimental findings, Dr. Fariborz’s work helps fill this critical gap. The new theoretical structure not only enhances our understanding of hadronic matter but also offers a flexible foundation that can evolve with future discoveries in particle physics.
