Experiment to Precisely Measure Electrons Moves Forward

The MOLLER experiment at DOE’s Jefferson Lab is one step closer to carrying out an experiment to gain new insight into the forces at work inside the heart of matter through probes of the humble electron. The experiment has just received a designation of Critical Decision 1, or CD-1, from the DOE, which is a greenlight to move forward in design and prototyping of equipment.

Scientists achieve higher precision weak force measurement between protons, neutrons

Through a one-of-a-kind experiment at Oak Ridge National Laboratory, nuclear physicists have precisely measured the weak interaction between protons and neutrons. The result quantifies the weak force theory as predicted by the Standard Model of Particle Physics.
