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 ...

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 ...

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 ...

While the Higgs mechanism was confirmed by the Large Hadron Collider—leading to the 2013 Nobel Prize—it fails to account for ...

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 ...

A heavy, strange cousin of the proton has been seen a second time, but it seems to have lost a little weight. The omega-b-minus, also called the omega-sub-b baryon, is a three-quark particle related ...

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 ...

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 ...

NEWPORT NEWS, VA – 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 ...
