Two extremely precise experiments agree with a previously shocking measurement of just how big the proton is, which may help ...

A lot of the science from our accelerators is published long after collisions end, so storing experimental data for future physicists is crucial. About a billion pairs of particles collide every ...

No one has ever probed a particle more stringently than this. In a new experiment, scientists measured a magnetic property of the electron more carefully than ever before, making the most precise ...

A subatomic particle long predicted by theorists has finally been observed, ending a decades-long wait in physics. Named Ξcc+ ...

When fundamental particles are heavier or lighter than expected, physicists' understanding of the universe can tip into the ...

An MIT-led team has found that data from “near-misses” at the Large Hadron Collider, long dismissed as background noise, can ...

The magnum opus of particle physics is far from complete, requiring physicists to devise many alternatives—some weirder than others. Reading time 5 minutes For all practical purposes, the Standard ...
