"Upcoming Measurements of the Neutron Lifetime to 1 Second and Why You Should Care"
 Slideshow (PDF)

The decay of the free neutron is the archetypal charged current semi-leptonic weak process. As such, experimental investigation of the decay process through lifetime and decay correlation measurements provide insight into a wide variety of physics, ranging from fundamental interactions to the formation of the early Universe. I will discuss some of the history of neutron decay measurements, the neutron lifetime's role in big bang nucleosynthesis, and my work on the upcoming in-beam measurement of the neutron lifetime at the NIST Center for Neutron Research.
