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 ...

If you ask how much an object like a bicycle weighs, there’s a simple answer. But if you ask where the mass of a bicycle is, things get more complex. The bike has a lot of parts—some of which ...

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 ...

"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 ...

The whole is equal to the sum of its constituent parts. That's how everything works, from galaxies to planets to cities to molecules to atoms. If you take all the components of any system and look at ...

July 21 (UPI) --A team of scientists from Germany and Japan have recorded the most precise measurement of a proton's mass. Researchers accomplished the feat by trapping a proton in a super sensitive ...

Only 1% of the mass of the proton comes from the Higgs field. ALICE scientists examine a process that could help explain the rest. When protons and nuclei inside the Large Hadron Collider smash ...

The most precise measurement ever of the mass of the proton suggests that the particle is a tiny bit lighter than the current accepted value. Although the difference is less than one part in 10 ...

The next time you step on bathroom scales, remember that it’s not your big bone structure or that extra helping of pudding that makes you heavy, it’s the motion of the quarks and gluons buzzing around ...

The proton has lost a little of its bulk. A fresh attempt to pin down its mass, with three times the precision of the previous best try, finds that the subatomic particle is 30 billionths of a per ...
