Vertex corrections and wavefunction renormalization for atoms, nuclei, and other heavy composite particles
Ryan Plestid, Mark B. Wise
We study QED corrections to operator matrix elements involving heavy composite particles (e.g., heavy-mesons, nuclei, and atoms). We define a new notion of reducible and irreducibl…

Atomic binding corrections for high energy fixed target experiments
Ryan Plestid, Mark B. Wise
High energy beams incident on a fixed target may scatter against atomic electrons. To a first approximation, one can treat these electrons as at rest. For precision experiments, ho…

Final state interactions for high energy scattering off atomic electrons
Ryan Plestid, Mark B. Wise
We consider the scattering of high energy leptons off bound atomic electrons focusing primarily on final state interactions i.e., the exchange of virtual photons between the outgoi…
