It's a twenty-year-old question: how much do the constituent quarks and gluons contribute to the spin of a nucleon? New results from the COMPASS experiment add to the picture. Naively, the proton ...

Get Instant Summarized Text (Gist) The investigation into the proton's spin, specifically the contribution from gluons, suggests that a negative gluon polarization (∆g) is now less likely. Using ...

T he atomic nucleus is made up of protons and neutrons, particles that exist through the interaction of quarks bonded by gluons. It would seem, therefore, that it should not be difficult to ...

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 ...

Nuclear physics research is focused on understanding the matter composed of quarks and gluons, which makes up 99% of the mass of the universe. Most of this matter is found at the core of atoms, the ...

It has been discovered that quantum entanglement in the proton is maximal, and that its main sources are constantly ‘boiling’ seas of virtual gluons and quarks. In the article just published ...

Scientists have recently made a significant breakthrough in understanding the structure of matter. For the first time, they ...

(A) ELECTRON-POSITRON COLLISIONS: WHEN ELECTRONS AND POSITRONS COLLIDE, THE RESULTING QUARKS AND GLUONS UNDERGO HADRONIZATION, FORMING COLLIMATED STREAMS OF PARTICLES KNOWN AS JETS. (B) GRAPH ...

In 2023, when Daniel Marx, Deputy Group Leader of the EIC Accelerator Design Group at BNL, traveled to Washington to ...

That’s because quarks and their counterpart gluons are the small pieces of the puzzle that make up the nucleons in an atom. And the only way to see them is to split open atoms. The problem ...
