Description
We investigate the renormalization properties of an EFT scheme for two-neutron halo nuclei with weak neutron-core interaction proposed by Hongo and Son. In this theory, there is a universal prediction for the ratio of the mean-square matter radius and charge radius. We find that one further renormalization input is required to predict both radii separately. Using one of the radii as this input, we quantify the restriction on the UV cutoff from the Landau pole. We apply our results to the case of ${}^{22}\mathrm{C}$ as well as other two-neutron halo nuclei and discuss the hierarchy of scales implicit in the power counting. We compare our findings with results obtained from standard Halo-EFT calculations.
