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 ...

Dark matter may be invisible, but scientists are getting closer to understanding whether it follows the same rules as ...

The Large Hadron Collider (LHC) sparked worldwide excitement in March as particle physicists reported tantalizing evidence for new physics — potentially a new force of nature. Now, our new result, yet ...

In our Universe, a left hand reflected in a mirror or pond appears to be a right hand. While most of the laws of nature are symmetric under reflections, obeying the same rules, the weak interactions ...

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 ...

Does dark matter follow the same laws as ordinary matter? The mystery of this invisible and hypothetical component of our ...

Measuring the mass of W bosons took 10 years – and the result was not what physicists expected. PM Images/Digital Vision via Getty Images “You can do it quickly, you can do it cheaply, or you can do ...

Physics has a reputation for being dominated by men, especially a century ago, as quantum physics was just being invented – ...
