Description
In this poster presentation, I will discuss the two-photon exchange (TPE) as a crucial higher-order contribution to lepton-proton scattering and the theory of light muonic atoms. In particular, I will focus on the proton polarizability contribution as the dominant uncertainty in the theory prediction of the Lamb shift and the hyperfine splitting (HFS) in muonic hydrogen ($\mu$H). It is important to provide the best possible theoretical estimate for the TPE correction to guide the upcoming high-precision measurements of the $\mu$H ground-state HFS.
