To Understand a Special Hadron, Researchers Turn to Supercomputers and Quantum Chromodynamics

The short-lived hadron resonance lambda 1405 was predicted in the late 1950s and early 1960s, then confirmed experimentally later in the 1960s. This resonance has unusual properties that make it an important subject for nuclear physics studies. In...

Gluons鈥� Density Isn鈥檛 the Same in Bound vs Unbound Protons and Neutrons

Nuclear physicists recently used photons emitted by an accelerated gold nucleus to probe the inner structure of the protons and neutrons (nucleons) in another gold nucleus to measure the resulting density of gluons. The research found that nucleons...
