Partial-wave unitarity and long-range interactions
Ryan Plestid, Pablo Quílez Lasanta
Theories with massless particles contain -channel (forward scattering) singularities that cause standard fixed order expressions for partial-wave amplitudes to be ill-defined. T…
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…
The effective field theory of extended Wilson lines
Ryan Plestid
We construct the effective theory of electrically charged, spatially extended, infinitely heavy objects at leading power. The theory may be viewed as a generalization of NRQED for…
Generalized eikonal identities for charged currents
Ryan Plestid
We discuss QED radiative corrections to contact operators coupling two heavy fields and one light field. New eikonal identities are derived in the static limit that demonstrate the…
