WebbThe main idea of EFT is to build a theory which works within the momentum scale of interest without knowing or assuming physics in other places. Therefore, a prerequi-site … Webbof pionless EFT, all higher-order corrections, including attractive P-wave channels, are perturbative. Thus we do not expect higher-order corrections to alter the low-energy …
