Description

Recently the muonic hydrogen lamb shift has been measured with unprecedented accuracy [R. Pohl et al, Nature vol. 466, p. 213 (2010)], allowing for a precise determination of the proton radius. This determination is 5 sigma away from the previous CODATA value obtained from (mainly) the hydrogen lamb shift and the electron-proton scattering. Within an effective field theory formalism, I will define the proton radius and review the theoretical prediction for the muonic hydrogen lamb shift studying both the pure QED-like computation and the hadronic effects.
