The radius of the proton, generally assumed to be a well measured and understood quantity has recently come under scrutiny due to highly precise, yet conflicting, experimental results. These new results have generated a host of interpretations, none of which are completely satisfactory.
I will discuss the existing results, focusing on the discrepancy
between the various extractions. I will briefly discuss some theoretical
attempts at resolution and focus on new scattering measurements, both
planned and already underway, that are attempting to resolve the
puzzle.
