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 ...
The smallest named unit in the metric system is the yoctogram, equal to 0.000000000000000000000001 grams. (Yes, that's 24 zeros.) For a scale that can measure differences in mass as small as a ...
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 ...

Scientists at Yale University use customised mass spectrometer to establish experimental benchmarks that will inform chemical ...
Why do some elements decay in minutes, while others last billions of years? Certain "magic numbers" of nuclear particles may make all the difference.
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 ...
