gluons

The two-dimensional spatial distribution of mass due to gluons in the nucleon (left) and the pion (right), simulated at seven valence pion masses with lattice quantum chromodynamics.

Mass Distribution Inside Subatomic Particles Mapped for First Time

Categories Physics & Mathematics

A global analysis of experimental data and lattice Quantum Chromodynamics calculations provides insight into the role of the gluons (purple squiggles) contributing to the spin of the nucleon. Gluons are manifestations of the

Theory and experiment combine to shine a new light on proton spin

Categories Physics & Mathematics

A proton’s valence quarks (blue, red, and green), quark-antiquark pairs, and gluons (springs). Scalar gluon activity (pink) extends beyond the electric charge radius (orange) that surrounds the gluonic energy core (yellow).

Scientists Locate the Missing Mass Inside the Proton

The house-size Solenoidal Tracker at RHIC (STAR) detector at the Relativistic Heavy Ion Collider (RHIC) acts like a giant 3D digital camera to track particles emerging from particle collisions at the center of the detector.

New type of entanglement lets scientists ‘see’ inside nuclei
