Scientists have long tried to experimentally demonstrate a certain symmetry property of the weak interaction—parity violation—in molecules. So far, this has not been possible. A new interdisciplinary ...

In the very first microseconds of the Big Bang, something strange happened. Matter somehow outnumbered antimatter and kept the fledgling universe from annihilating itself. This break with conventional ...

Parity violation in molecular systems arises from the subtle breaking of spatial inversion symmetry by the weak force, one of the four fundamental interactions. In chiral molecules—those that exist in ...

A reflection always reproduces objects as a complete mirror image, rather than just its individual parts or individual parts in a completely different orientation. It's all or nothing, the mirror ...

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).

WASHINGTON, Oct. 18 – Exploring the fundamental laws of physics has often required huge accelerators and particles colliding at high energies. But table-top experiments, usually employing exquisitely ...

Why the universe is dominated by matter today, instead of being comprised of equal parts matter and antimatter, is one of the most intriguing questions in all of science. One of the conditions ...

Chien-Shiung Wu, one of the greatest experimental physicists in history, is honored on February 11, 2021 with the debut of a new forever stamp that bears her likeness. Wu experimentally discovered ...
