An experiment with a single electron, trapped for months on end, produced one of the most precise tests yet of the standard model of particle physics.

Caltech scientists have found a fast and efficient way to add up large numbers of Feynman diagrams, the simple drawings ...

Scientists are on the trail of a mysterious five-particle structure that could challenge one of the biggest theories in ...

There are also rumblings through other sectors of particle physics, like neutrino research, of observations of particle behavior not quite adding up with the Standard Model’s predictions.

The Standard Model is the modern physical understanding of three of the four forces of nature: electromagnetism, the strong nuclear force and the weak nuclear force.

Physicists at ETH Zurich in Switzerland have a novel plan to uncover an unknown fifth force of nature long theorized to exist ...

If photons possess more quantum states than expected, it would overhaul our understanding of all particle physics – and now physicists have identified a way to test this radical idea in an ...

The standard model of particle physics is often illustrated as a simple grid showing the 17 basic particles (shown above). But an alternative way of visualising it reveals the complex rules that ...

The Standard Model is our best theory for how the universe operates, but there are some missing pieces that physicists are struggling to find.

New measurement of wobbling muons back up previous findings – potentially challenging the Standard Model of Particle Physics.
