Abstract:
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.
