Nuclear physicists may have finally pinpointed where in the proton a large fraction of its mass resides. A recent experiment carried out at the U.S. Department of Energy's Thomas Jefferson National ...

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 ...

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 ...
