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 ...

Through a one-of-a-kind experiment at the Department of Energy's Oak Ridge National Laboratory, nuclear physicists have precisely measured the weak interaction between protons and neutrons. The result ...

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 ...

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 ...

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 ...
