New Insights into Nucleon Resonances: Unveiling the 3D Structure
In a recent study, researchers have made significant progress in understanding the 3D structure of nucleon resonances. These resonances, exhibited by protons and neutrons, are crucial in unraveling the mysteries of the early universe following the Big Bang.
Protons and neutrons, known as nucleons, are fundamental building blocks of matter. They consist of three quarks tightly bound by the strong nuclear force. While the most stable state of a nucleon is its ground state, it can be excited into a higher-energy state, leading to quark rotations and vibrations, resulting in nucleon resonances.
A team of physicists from Justus Liebig Universitat (JLU) Giessen in Germany and the University of Connecticut conducted an experiment to explore nucleon resonances at the Jefferson Lab’s Continuous Electron Beam Accelerator Facility (CEBAF). The results of their research have opened new avenues for investigating the 3D structure of resonating protons and the excitation process.
Stefan Diehl, the leader of the analysis, emphasized the importance of their work in shedding light on the fundamental properties of nucleon resonances. He described it as just the beginning, with this measurement marking the start of a new field of research.
The experiment involved high-energy electron beams colliding with hydrogen gas to create nucleon resonances, leaving behind detectable particles that provided insights into their existence.
These findings have already sparked interest in the scientific community, leading to further investigations and publications. The team plans to conduct more experiments to explore different characteristics of the scattering process, helping physicists better understand the early universe’s formation and evolution.
Diehl emphasized that these studies will provide valuable information about the formation of matter in the universe and its current state. This research was funded by the US Department of Energy.
By delving into the world of nucleon resonances, scientists are not only uncovering the secrets of the early cosmos but also gaining a deeper understanding of the universe’s origins and evolution.
