Physicists in Germany have carried out the most accurate measurement to date of the width of the proton. By examining a ...

After years of confusion, a new study confirms the proton is tinier than once thought. That enables a test of the standard model of particle physics.

It’s often said in science that extraordinary claims require extraordinary evidence. Recent measurements of the mass of the elementary particle known as the W boson provide a useful case study as to ...

Learn about the Standard Model of particle physics and how physicists use it to predict the (subatomic) future. In ancient times, Greeks interested in forecasting the future would voyage on the ...
