Nonradiative alpha(7)m QED effects in the Lamb shift of helium triplet states
Original language description
Theoretical predictions for the Lamb shift in helium are limited by unknown quantum electrodynamic effects of the order alpha(7)m, where a is the fine-structure constant and m is the electron mass. We make an important step towards the complete calculation of these effects by deriving the most challenging part, which is induced by the virtual photon exchange between all three helium particles, the two electrons and the nucleus. The complete calculation of the alpha(7)m effect including the radiative corrections will allow comparing of the nuclear charge radii determined from the electronic and muonic helium atoms and thus provide a stringent test of the standard model of fundamental interactions.
