  1. 19. Proton radius puzzle: theory vs experiment

    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.
