Abstract

The rigorous on-shell $T$ -matrices for $NN$ scattering in the coupled channels $^3S_1$ $-$ $^3D_1$ are briefly presented in the context of EFT( $\not\pi$ ) with the contact potentials truncated at order $\Delta=4$ . The nonperturbative features of renormalization are highlighted and elaborated. A simple scenario for EFT power counting's and renormalization prescriptions is also presented with its consequences being roughly analyzed and discussed.
