Proton radius puzzle: Measurement, Proposed resolutions & Problem

The proton radius puzzle was a problem in physics relating to the size of the proton. Historically the proton charge radius was measured by two independent methods, which converged to a value of about 0.877 fm. This value was challenged by a 2010 experiment using a third method, which produced a radius about 4% smaller than this, at 0.842 fm. New…
