Of the four known fundamental forces of nature, the weak nuclear force is the one with the least obvious purpose. Gravity ...

A new result from the Q-weak experiment at the Department of Energy’s Thomas Jefferson National Accelerator Facility provides a precision test of the weak force, one of four fundamental forces in ...

A spinning neutron disintegrates into a proton, electron, and antineutrino when a down quark in the neutron emits a W boson and converts into an up quark. The exchange of quanta of light (γ) among ...

What if the universe remembers? A bold new framework proposes that spacetime acts as a quantum memory. For over a hundred ...

A clever mathematical tool known as virtual particles unlocks the strange and mysterious inner workings of subatomic ...

Steven Weinberg ’54, the theoretical physicist whose Nobel prize-winning work transformed scientists’ understanding of fundamental forces, died on July 23. He was 88. “[His work] is basically the ...

For over 50 years, physicists have generally agreed that the interactions between elementary particles are governed by four fundamental forces: the strong force, weak force, electromagnetic force and ...

The W boson, one of the tiniest, most elementary particles in the known universe is causing a big ruckus in the field of particle physics. According to the Standard Model, W bosons (together with ...
