Researchers have been working for decades to understand the architecture of the subatomic world. One of the knottier questions has been where the proton gets its intrinsic angular momentum, otherwise ...

"Once we figured out that these black holes form in a quark-gluon plasma, the most important thing we had to figure out was, ...

For many years, exact measurements of the proton's electric charge response ... used a small color dipole (the J/Psi particle) to reveal a spherical size and location of the gluons’ mass and ...

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 ...

Scientists believe such a substance of free quarks and gluons, the building blocks of protons and neutrons, permeated the universe a fraction of a second after the Big Bang. RHIC's energetic ...
