Title:     Nuclear structure and the proton radius puzzle

Abstract: The charge radius of the proton was recently extracted from precision spectroscopy of muonic hydrogen. The result disagrees by 7 sigma with the CODATA value, leading to the "proton radius puzzle". To further investigate this, similar measurements were performed in other light muonic atoms, where the uncertainty in nuclear structure corrections determine the attainable precision of the extracted charge radii. We have performed first ab-initio calculations of the nuclear structure corrections relevant for these on-going experiments, reducing their uncertainties from ~20% to a few percent.
