Brief review of the proton radius problem is given. In the framework of the quasipotential method in quantum electrodynamics we calculate the contribution of light pseudoscalar (PS) and axial-vector (AV) mesons to the interaction operator of a muon and a proton in muonic hydrogen atom. The coupling of mesons with the muon is via two-photon intermediate state. The parametrization of the...

I will discuss the present status of the determination of the proton radius. Starting with 2010 there is a controversy within the results obtained from electron-proton scattering, hydrogen and deuterium spectroscopy and spectroscopy of muonic hydrogen and deuterium.I will briefly review the situation and its recent development.
