Interedge channel interactions in the quantum Hall regime at filling factor nu=2 are analyzed within a plasmon scattering formalism. We derive analytical expressions for energy redistribution among edge channels and for high-frequency noise, which are shown to fully characterize the low energy plasmon scattering. In the strong-interaction limit, the predictions for energy redistribution are compared with recent experimental data and found to reproduce most of the observed features. Quantitative agreement can be achieved by assuming 25% of the injected energy is lost toward other degrees of freedom, possibly the additional gapless excitations predicted for smooth edge potentials.
