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 ...

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 ...

In nuclear beta decay an up quark ‘u’ in a proton converts into an up down quark ‘d,’ turning the proton into a neutron and emitting a positron and a neutrino. This work affects interpretation of beta ...

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 ...
