For the past half century or so, a theory known by the understated name of the Standard Model has dominated the field of particle physics. This theory provides us with a detailed description of the 17 ...

Physicists know that their elegant theoretical description of forces and particles — the standard model of particle physics — ...

In 1930, a young physicist named Carl D. Anderson was tasked by his mentor with measuring the energies of cosmic rays—particles arriving at high speed from outer space. Anderson built an improved ...

Particle physics has always proceeded in two ways, of which new particles is one. The other is by making very precise measurements that test the predictions of theories and look for deviations from ...

Mystery no more Artist’s conception of the magnetic moment of the muon – a sub-atomic particle similar to, but heavier than, the electron. More than half a century of measurements of that fundamental ...

An unexpected behavior in a particle decay seems to disagree with the predictions of the Standard Model, despite its high ...

If you ask a physicist like me to explain how the world works, my lazy answer might be: “It follows the Standard Model.” The Standard Model explains the fundamental physics of how the universe works.

The muon is often described as the electron's heavy cousin. A more appropriate description might be its rogue relation. Since its discovery triggered the words "who ordered that" (Isidor Isaac Rabi, ...
