Self-consistent computation of pair production from non-relativistic effective field theories in the Keldysh-Schwinger formalism
Self-consistent four-point functions in NR EFT with Keldysh-Schwinger formalism render Sommerfeld unitarization temperature-dependent and keep bound states on-shell in out-of-equilibrium decay even with finite-width B...
