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 Quantum Chromodynamics (QCD). EFTs in this sequence are expansions around different low-energy limits of QCD, each with its own characteristics, scales, and ranges of applicability regarding energy and number of nucleons. We review each of the three main nuclear EFTs -- Chiral, Pionless, Halo/Cluster -- highlighting their similarities, differences, and connections. In doing so, we survey the structural properties and reactions of nuclei that have been derived from the ab initio solution of the few- and many-body problem built upon EFT input.

Deuterium-Proton Fusion in an Effective Field Theory Constructed from On-Shell Amplitudes
A nuclear-state on-shell EFT yields S(0)=0.209±0.008 eV b for d(p,γ)3He and traces the ab initio-data offset to a natural t_E1≈−0.15 contact term.

Constructing Effective Interactions via Projection-Based Inversion
Discrete energy levels from truncated many-body calculations are inverted, via a Multiparameter Eigenvalue Problem emulator, into effective contact interactions that yield scattering phase shifts and resonance predictions.

Perturbative calculations of nucleon-deuteron elastic scattering in chiral effective field theory
A fixed-kernel perturbation framework computes nucleon-deuteron scattering up to next-to-leading order in chiral EFT, benchmarked against wave-packet continuum discretization.

Short-distance production of three particles with large scattering length
Short-distance production of three neutrons in pionless EFT is dominated by the P-wave and shows no resonance-like structure; three bosons show Efimov-resonance peaks, and effective-range corrections are small.

Quantum Monte Carlo calculation of $\delta_{\rm NS}$ in $^{10}$C using an effective field theory approach
The first quantum Monte Carlo evaluation of the nuclear-structure-dependent radiative correction in carbon-10 confirms the NCSM dispersion result, with the residual uncertainty set by two undetermined low-energy constants.

Hypernuclei with Neural Network Quantum States
Neural network quantum states, extended to include Lambda hyperons, reproduce hypernuclear separation energies to within roughly 9% and predict the observed proton-radius shrinkage in 7ΛLi.

The breakdown scale of pionless effective field theory in the three-nucleon sector
Bayesian analysis of NLO and N2LO neutron-deuteron cross sections places the pionless EFT breakdown scale near 100 MeV, and combining with neutron-proton data shifts the mode close to the pion mass.

From bare two-nucleon interaction to nuclear matter and finite nuclei in a relativistic framework
A leading-order relativistic chiral two-nucleon force, with four constants fit to scattering data, describes nuclear matter saturation and medium-mass nuclei binding energies and radii without three-nucleon forces.

Investigating the two-pion exchange of the double charm $DD^*$ chiral interactions and $T_{cc}$
In this chiral EFT calculation the I=0 DD* two-pion-exchange potential is repulsive, and its near-cancellation with attractive contact and one-pion terms provides the weak binding of Tcc.

From Nuclear Matter with Quenched $g_A$ to Compact-Star Matter with a Signal for Emergent Hidden Scale Symmetry
The paper argues that quenched g_A ≈ 1 in nuclei and the pseudo-conformal sound speed v_s^2/c^2 ≈ 1/3 in compact stars are parallel signals of one emergent hidden scale symmetry.
