In the world of nuclear physics, protons often take the spotlight. But now, for the first time, the neutron has stepped into ...

Ed Kinney: My research is focused on the elucidation of how the basic constituents of the nucleon, quarks, are bound in a gluonic field. At present, we still have only basic one-dimensional momentum ...

ATLAS has now confirmed that top quarks are produced in the lead-nucleus collisions, together with their antiparticles. The top quark’s fleeting interactions with the quark–gluon plasma could ...

Soon afterwards, the existence of quarks was confirmed experimentally ... Denniston et al, Modification of Quark-Gluon Distributions in Nuclei by Correlated Nucleon Pairs, Physical Review Letters ...

Comparing the number of direct photons emitted when proton spins point in opposite directions (top) with the number emitted when protons collide head-to-tail (bottom) revealed that gluon spins ...

I am a theoretical physicist interested in the strong interactions, the part of the Standard Model responsible for the confinement of quarks and gluons into protons, neutrons, nuclei and related ...

Protons also contain another kind of fundamental particle that acts like glue between quarks. It’s called a gluon. The quarks trade gluons back and forth. Protons trade gluons with neutrons and ...

called quarks and gluons. These are collectively known as partons. But how these partons are arranged inside the nucleon, and how they add up to produce the nucleon’s spin, remains unclear.
