The theoretical status on universal aspects of weakly-bound neutron-rich light nuclei are
reviewed, considering few-body approaches. We focus the review on the low-energy …

We discuss the subleading contact interactions, or counterterms, of the triplet channels of
nucleon-nucleon scattering in the framework of chiral effective field theory, with S and P …

We discuss conceptual aspects of renormalization in the context of effective field theories for
the two-nucleon system. It is shown that, contrary to widespread belief, the renormalization …

We study the nucleon-nucleon interaction up to next-to-next-to-leading order using time-
ordered perturbation theory in the framework of manifestly Lorentz-invariant chiral effective …

Motivated by the successes of relativistic theories in studies of atomic/molecular and nuclear
systems and the need for a relativistic chiral force in relativistic nuclear structure studies, we …

We discuss the connection between the perturbative and non-perturbative renormalization
and related conceptual issues in the few-nucleon sector of the low-energy effective field …

Continuing our effort to build a consistent power counting for chiral nuclear effective field
theory (EFT), we discuss the subleading contact interactions, or counterterms, in the singlet …

We discuss in this Brief Report the subleading contact interactions, or counterterms, in the 3
P 0 channel of nucleon-nucleon scattering up to O (Q 3), where, already at leading order …

We use a toy model to illustrate how to build effective theories for singular potentials. We
consider a central attractive 1/r2 potential perturbed by a 1/r4 correction. The power …

We present a new rearrangement of short-range interactions in the S 0 1 nucleon-nucleon
channel within chiral effective field theory. This is intended to address the slow convergence …
