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…

Manifest Gauge Invariance for Structure Dependent Radiative Corrections to Processes Involving Atoms and Nuclei
Ryan Plestid, Mark B. Wise
Radiative corrections to reactions involving atoms or nuclei can become sensitive to the structure of the bound state. Generically, one encounters correlation functions of multiple…
