Recent progress in theoretical QCD has opened the way to connecting questions about the structure of particles like the proton with high-energy particle collision measurements. As theorists ...

Researchers have been working for decades to understand the details of where the proton gets its intrinsic angular momentum, ...

Quantum Chromodynamics (QCD) is the theory that describes ... between the contributions of quarks and gluons to the proton's overall structure[2]. This work is paving the way for a deeper ...

Protons are far from simple particles — they are swirling cauldrons of quarks, gluons, and quantum entanglement. Scientists ...

Quantum Chromodynamics (QCD) is the theory that describes the ... the complexity of quark dynamics and their role in the proton's structure. Moreover, the application of light-front quantization ...

As theorists generate new ideas about QCD, other researchers plan experiments to test those ideas. These tests involve colliding particles like electrons and protons at high energies and then ...
