"Revealing the Strong Force: New Insights into Proton Physics"

Physicists have used 50-year-old predictions about gravity's impact on subatomic particles to measure a second mechanical property in the proton, revealing the shear stress on the proton's quarks. By exploiting decades-old data and deeply virtual Compton scattering, the team successfully measured the strong force's distribution within the proton, providing insights into its structure and potential for discovering new physics. This breakthrough could lead to a deeper understanding of proton properties and pave the way for future measurements in the field of nuclear science.
