A proton’s valence quarks (blue, red, and green), quark-antiquark pairs, and gluons (springs). Scalar gluon activity (pink) extends beyond the electric charge radius (orange) that surrounds the ...

Inside the most powerful particle colliders on Earth, protons slam together at nearly the speed of light, shredding matter ...

A collaboration of nuclear theorists has used supercomputers to predict the spatial distributions of charges, momentum, and other properties of 'up' and 'down' quarks within protons. The calculations ...

A view inside a proton moving at nearly the speed of light toward the viewer with its spin pointing horizontally shows differences in the spatial distributions of the momentum of up (left) and down ...

"Hearst Magazines and Yahoo may earn commission or revenue on some items through these links." Researchers just found out where the secret mass of protons is located. Physicists have long known that ...

What makes up the matter we perceive in the universe? To start, there are the usual suspects, like electrons, protons, quarks and neutrinos. But if those particles aren't strange enough for you, I'm ...

An analysis by physicists of colliding protons is tackling the mystery of where protons get their intrinsic property known as spin. Along with neutrons, protons are housed inside an atom's nucleus.

Physics at the smallest scales is a challenge of observation: Particles are often fleeting, and the forces that govern their behavior are nearly imperceptible. But now, by exploiting decades-old data ...

Nuclear physicists may have finally pinpointed where in the proton a large fraction of its mass resides. A recent experiment has revealed the radius of the proton's mass that is generated by the ...

Quantum physics is usually associated with particle colliders and vacuum chambers, not with the proteins quietly shuttling energy inside our cells. Yet a new line of research argues that protons in ...
