Standard Model Gets Right Answer for Proton, Neutron Masses
from Science News
When it comes to weighty matters, quarks and gluons rule the universe, a new study confirms.
One of the largest computational efforts to calculate the masses of protons and neutrons shows that the standard model of particle physics predicts those masses with an uncertainty of less than 4 percent.
