Physical Review Letters, PRL, the world’s premier physics letter journal, has published two papers by a team of Louisiana State University nuclear physics researchers to advance the knowledge on the ...

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 ...

Theorists find new electromagnetic effects that shift the spin-dependent coupling of the nucleon to the weak force and point out the implications for new physics in beta decay. Outside atomic nuclei, ...

Physicists have found that an elementary particle called the W boson appears to be 0.1 percent too heavy—a tiny discrepancy that could foreshadow a huge shift in fundamental physics. The measurement, ...

A new surprising result from digging in Fermilab archives could help scientists uncover new laws of physics and solve mysteries such as the nature of dark matter. In a new study appearing in the April ...

The W boson is heftier than anyone expected. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. An ultraprecise measurement of the mass of a ...

Today, the universe as we know it is governed by four fundamental forces: the strong nuclear force, the weak nuclear force, electromagnetism, and gravity. However, these four forces aren’t exactly as ...

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 ...

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 ...
