The international collaboration, which includes researchers from the University of Adelaide, is focused on uncovering the structural complexity of subatomic particles to gain deeper insights into the forces that shape the universe.
"We have employed an advanced computational technique known as lattice quantum chromodynamics to chart the internal forces within a proton," explained Associate Professor Ross Young, Associate Head of Learning and Teaching at the School of Physics, Chemistry and Earth Sciences.
"This method segments space and time into a fine grid, enabling us to simulate variations in the strong force-the fundamental interaction that binds quarks within protons and neutrons-across different regions inside the proton."
The findings represent one of the most refined force field maps of nature ever produced. The study has been published in the journal *Physical Review Letters*.
The calculations, led by University of Adelaide PhD student Joshua Crawford, played a central role in the research, alongside his university team and international collaborators.
"Our study demonstrates that even at these incredibly minute scales, the forces at play are enormous, reaching up to half a million Newtons-akin to compressing the weight of ten elephants into a space far smaller than an atomic nucleus," Crawford stated.
"These detailed force maps provide fresh perspectives on the proton's internal behavior, helping us understand its dynamics in high-energy collisions, such as those occurring at the Large Hadron Collider, and in experiments probing the fundamental structure of matter."
The Large Hadron Collider (LHC) is the world's most powerful particle accelerator, developed by the European Organization for Nuclear Research (CERN) in collaboration with over 10,000 scientists and multiple research institutions across more than 100 countries. It serves as a crucial tool for physicists testing various theories in particle physics.
"Edison didn't create the light bulb by trying to improve candles-he built upon centuries of research on the interaction between light and matter," noted Associate Professor Young.
"In a similar manner, our modern exploration of subatomic forces is shedding light on how fundamental building blocks of matter behave under the influence of light, enhancing our understanding of the natural world.
"As we continue to unravel the proton's structure, we may refine applications that utilize protons in advanced technologies.
"One notable example is proton therapy, which harnesses high-energy protons to precisely target tumors while limiting damage to surrounding healthy tissue.
"Just as the early study of light laid the foundation for the development of lasers and imaging technologies, improving our understanding of proton interactions could drive the next generation of scientific and medical advancements.
"By visualizing the previously invisible forces within the proton, this research bridges the gap between theoretical physics and experimental observations-much like earlier scientific discoveries on light paved the way for transformative technological innovations."
