Description
In this talk, I would like to discuss the theory of light muonic atoms in view of upcoming experiments, e.g., the measurement of the muonic-hydrogen ground-state hyperfine splitting with ppm accuracy. A particular focus will be on predictions of the two-photon-exchange corrections in muonic hydrogen. The leading-order baryon chiral perturbation theory predictions of the proton polarizability contribution will be compared to recent data-driven dispersive analysis.
