In 2010 the first measurement of the proton charge radius from spectroscopy of muonic hydrogen was found to be five standard deviations away from the regular hydrogen value.
Almost six years later, this "proton radius puzzle" is still unresolved.
The proton radius puzzle has led to a reevaluation of the extraction of proton radii from scattering and spectroscopy data.
I will
describe some of these developments and their implications to
neutrino-nucleus scattering. One of the most promising avenues to test
the muonic hydrogen result is a new muon-proton scattering experiment
called MUSE. I will describe how effective field theory methods will
allow us to connect muonic hydrogen spectroscopy to muon-proton
scattering in a model-independent way.
