Understanding the origin of the mass of subatomic particles like protons and neutrons is a major challenge in modern physics.

Research on trace anomaly in nucleons and pions uncovers mass distribution patterns, crucial for understanding quark binding ...

In a study published in Physical Review D scientists calculated the trace anomaly for both nucleons (protons or neutrons) and ...

Scientists have uncovered new details about how mass is distributed inside tiny particles called hadrons, such as protons, ...

Since a nucleus contains protons and neutrons, most of the mass of an atom is concentrated in its nucleus.
