“The Fundamental Properties of the Neutron,  or Why do we keep measuring the same things over and over again?”

 

 

 

Abstract: 

The fundamental properties of elementary particles, such as their masses, lifetimes, and magnetic moments are key parameters in many physical models and their precise values are frequently used to benchmark fundamental theories.  As a result, it seems clear that continued improvement in the accuracy of their determinations is a worthwhile endeavor. Nonetheless, it is fair to question the value of improved accuracy simply for “its own sake.” In this talk, I will give a review a few of the fundamental properties of the neutron and show how their experimental determinations have impacted theory, sometimes in unexpected ways. I will also briefly discuss the estimation of experimental error with particular attention to the disconcertingly frequent “high sigma” discrepancies that occur among measurements by different methods
