Improved Actions for Nuclear Effective Field Theories
U. van Kolck
Effective field theories have been successful in describing nuclei up to the alpha particle but face significant challenges for larger nuclei due to leading-order instabilities. Th…
Limits on an improved action for contact effective field theory in two-body systems
L. Contessi, M. Pavon Valderrama, U. van Kolck
We consider a possible resummation of subleading effects in two-body systems with a large scattering length as described by a short-range effective field theory (EFT). In particula…
Universality of Three Identical Bosons with Large, Negative Effective Range
Harald W. Griesshammer, Ubirajara van Kolck
"Resummed-Range Effective Field Theory'' is a consistent nonrelativistic effective field theory of contact interactions with large scattering length and an effective range $r_0…
Effective Field Theory for the Bound States and Scattering of a Heavy Charged Particle and a Neutral Atom
Daniel Odell, Daniel R. Phillips, Ubirajara van Kolck
We show the system of a heavy charged particle and a neutral atom can be described by a low-energy effective field theory where the attractive induced dipole potential dete…
Two-body double pole and three-body bound states: physical and unphysical quark masses
V. S. Timoteo, U. van Kolck
We solve the Faddeev bound-state equations for three particles with simple two-body nonlocal, separable potentials that yield a scattering length twice as large as a positive effec…
Weinberg and few-nucleon forces
U. van Kolck
Weinberg's contributions to the power counting and derivation of few-nucleon forces in Chiral EFT are briefly recalled. Subsequent improvements are reviewed, concluding with the re…
Nuclear Forces for Precision Nuclear Physics -- a collection of perspectives
Ingo Tews, Zohreh Davoudi, Andreas Ekström +42
This is a collection of perspective pieces contributed by the participants of the Institute of Nuclear Theory's Program on Nuclear Physics for Precision Nuclear Physics which was h…
The importance of few-nucleon forces in chiral effective field theory
C. -J. Yang, A. Ekström, C. Forssén +3
We study the importance of few-nucleon forces in chiral effective field theory for describing many-nucleon systems. A combinatorial argument suggests that three-nucleon forces -- w…
Nuclear Effective Field Theories: Reverberations of the early days
U. van Kolck
Effective field theories are recognized nowadays as the framework to describe low-energy nuclear structure and reactions consistently with the underlying theory of the strong inter…
Nucleon decay in the deuteron
F. Oosterhof, J. de Vries, R. G. E. Timmermans +1
We calculate the lifetime of the deuteron from dimension-six quark operators that violate baryon number by one unit. We construct an effective field theory for interaction…
Nuclear effective field theory: status and perspectives
H. -W. Hammer, S. König, U. van Kolck
The nuclear physics landscape has been redesigned as a sequence of effective field theories (EFTs) connected to the Standard Model through symmetries and lattice simulations of Qua…
Fate of the neutron-deuteron virtual state as an Efimov level
Gautam Rupak, Akshay Vaghani, Renato Higa +1
The emergence of Efimov levels in a three-body system is investigated near the unitarity limit characterized by resonating two-body interaction. No direct evidence of Efimov levels…

M. Sánchez Sánchez, C. -J. Yang, Bingwei Long +1
We present a new rearrangement of short-range interactions in the nucleon-nucleon channel within Chiral Effective Field Theory. This is intended to reproduce the amplitude…

L. Contessi, A. Lovato, F. Pederiva +3
We extend the prediction range of Pionless Effective Field Theory with an analysis of the ground state of O in leading order. To renormalize the theory, we use as input both…
Triton and Neutron-Deuteron Scattering up to Next-to-Leading Order in Chiral EFT
Young-Ho Song, Rimantas Lazauskas, U. van Kolck
Determination of the proper power-counting scheme is an important issue for the systematic application of Chiral Effective Field Theory in nuclear physics. We analyze the cutoff de…
Power Counting in Peripheral Partial Waves: The Singlet Channels
M. Pavón Valderrama, M. Sánchez Sánchez, C. -J. Yang +3
We analyze the power counting of the peripheral singlet partial waves in nucleon-nucleon scattering. In agreement with conventional wisdom, we find that pion exchanges are perturba…
Nuclear Physics Around the Unitarity Limit
Sebastian König, Harald W. Grießhammer, H. -W. Hammer +1
We argue that many features of the structure of nuclei emerge from a strictly perturbative expansion around the unitarity limit, where the two-nucleon S waves have bound states at…

An effective field theory is used to describe light nuclei, calculated from quantum chromodynamics on a lattice at unphysically large pion masses. The theory is calibrated at leadi…

C. J. Yang, M. Grasso, K. Moghrabi +1
Phenomenological effective interactions like Skyrme forces are currently used in mean--field calculations in nuclear physics. Mean--field models have strong analogies with the firs…
