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 ...

Recent advancements in nucleon research have significantly ... functions (PDFs), which map the distribution of quarks and gluons within protons and neutrons. By incorporating the phenomenon ...

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.

The aim is to form quark–gluon plasma (QGP) — a soup of quarks and gluons — and to study its properties. Heavy-ion physicists have waited many years for a facility such as RHIC, so the ...

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 ...

The proton mass radius is smaller than the electric charge radius (a dense core), while a cloud of scalar gluon activity extends beyond the charge radius. This finding could shed light on ...
