Abstract:
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.
More than five 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.
