Title:	Bound state QED and the proton radius puzzle
Abstract:	In view of the discrepancy between the value of the proton radius derived from the muonic hydrogen spectroscopy [R. Pohl et al, Nature 466 (2010) 213] and that derived from the atomic hydrogen spectroscopy we reexamine the theory of atomic bound states. We present a way of solving the bound-state problem based on the use of the generalized dynamical equation [R. Kh. Gainutdinov, J. Phys. A, 32 (1999) 5657]. Equations are derived that allow one to determine the QED corrections to the atomic energy levels and the state vectors without resorting to regularization and renormalization procedures. We found a new self energy correction to the atomic energy levels that can have a significant effect on the proton radius derived from the atomic spectroscopy. It is hoped that taking into account this corrections will remove the discussed discrepancy.
