David Armstrong studies a phenomenon that is ubiquitous in nature, yet only a few non-scientists know what it is. It’s called the weak force, or the weak interaction. Armstrong was recently named a ...

Chalk up another win for the Standard Model, the remarkably successful theory that describes how all the known fundamental particles interact. Physicists have made the most precise measurement yet of ...

In this video, we explore fundamental concepts about the atom and the forces that govern it. **CHAPTERS** 0:00 - Why is the ...

The weak nuclear force, or weak force for short, is so named because it is the direct contrast to the strong nuclear force, the attractive force that binds protons and neutrons to form the nucleus of ...

The weak force drives radioactive decays that diagnose disease and treat cancer, make your smoke detectors work, and indicate the age of ancient skeletons and tools. Providing a window on the weak ...

A new result from the Q-weak experiment provides a precision test of the weak force, one of four fundamental forces in nature. The proton's weak charge was found to be QWp=0.0719±0.0045, in excellent ...

An international collaboration of particle physicists has made new measurements that shed more light on the weak force, which is responsible for radioactive beta-decay. The results, which agree with ...

During the International Conference on High-Energy Physics (ICHEP 2020), the ATLAS collaboration presented the first observation of photon collisions producing pairs of W bosons, elementary particles ...

The Standard Model of Particle Physics is scientists' best understanding of the forces that describe how subatomic particles interact. The Standard Model encompasses four forces: the strong nuclear ...

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 team of scientists has for the first time measured the elusive weak interaction between protons and neutrons in the nucleus of an atom. They had chosen the simplest nucleus consisting of one neutron ...
