Proton structure in and out of muonic hydrogen
Abstract
In this talk, I will start with a short review of the proton radius puzzle and its present status, covering lepton-proton scattering, as well as hydrogen and muonic-hydrogen spectroscopy. After that, I will discuss the spectroscopy of light muonic atoms with a focus on nucleon- and nuclear structure corrections from two-photon exchange. As an outlook, I will briefly touch on the potential of atomic spectroscopy to test QED and nuclear theories, refine fundamental constants, and search for New Physics.
