Abstract
The particle-particle diffusion propagator is evaluated diagrammatically in two dimensions in the presence of inelastic electron-electron scattering due to paramagnon exchange. The paramagnon effect enters when there is a strong short-range opposite-spin Hubbard- type repulsion. An inelastic scattering rate 1/ ∝Tln min{(1-I)/T, τ} cuts off the backscattering divergence responsible for localization, where 1-I is the Stoner enhancement factor.
