Parity violation: image of galaxies taken by the James Webb Space Telescope. Astronomers have found evidence that parity violation in the early universe affects the distribution of galaxies today.

The bible of particle physics is dying for an upgrade. And physicists may have just the thing: Some particles and forces might look in the mirror and not recognize themselves. That, in itself, would ...

Parity violation in neutron physics represents a subtle but fundamentally important deviation from mirror symmetry in nuclear interactions. This phenomenon arises from the interplay between the weak ...

When a ‘scanner’ called Minnie van der Merwe handed Rosemary Brown a photographic slide with an unusual configuration of particle tracks, the physicist knew that she was on to something. “I looked ...

Physicists in the US have detected the largest atomic parity violation ever seen, in a ytterbium atom — 100 times greater than the largest effect to date observed in caesium atoms. With further work, ...

A central focus of our research program are several precision experiments that use parity-violating electron scattering to probe the structure of nucleons (the proton and the neutron).

Exploring the fundamental laws of physics has often required huge accelerators and particles colliding at high energies. But table-top experiments, usually employing exquisitely tuned lasers and ...
