We study the low-energy d- and d- elastic scattering using the halo effective field theory (EFT) formalism. For this purpose, we initially focus on the phase shift analysis of S- and P-wave scattering using the effective range expansion (ERE). Using the ERE analysis we determine the unknown EFT low-energy coupling constants and present the leading- and next-to-leading-order EFT results for the phase shift in each channel. Also, the differential cross section versus center-of-mass energy and angle are plotted with comparison to the available experimental data. Our results show good consistency with the present data.
