Quarks are the reason protons have a positive charge. Each quark has a fraction of an electric charge. A proton has two up ...

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

Brookhaven National Laboratory and Stony Brook University (SBU) have shown that particles produced in collimated sprays ...

Heaviest known elementary particles and their antimatter counterparts are detected after nuclear smash-ups at the Large Hadron Collider.

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 physics studies have discovered that quarks and gluons inside protons, which are subatomic positively charged ...

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 ...

Scientists say these quarks floated in a fluid-like force that held them all together inside their proton and neutrons. These particles, the researchers say, are called gluons. As such ...

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 ...

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 ...

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.
