Abstract:
The puzzle is easy to state: different ways of measuring the proton charge radius give different results, and the difference is seven standard deviations. Now four years after the discovery of this puzzle, the explanation is still not known. We will discuss how the measurements are made, and then will outline a selection of both ordinary and exotic proposals to explain the phenomenon.
