abstract
We review how nuclear forces emerge from low-energy QCD via chiral effective field theory. The presentation is accessible to the non-specialist. At the same time, we also provide considerable detailed information (mostly in appendices) for the benefit of researchers who wish to start working in this field.

First measurement of ^4_ΛHe yields in 3 GeV Au+Au collisions shows consistency with ^4_ΛH yields and JAM coalescence model while thermal model overpredicts absolute yields.
First extraction of complete NΔ vector and tensor couplings to ρ, b1, a2 from polarized πΔ photoproduction using a Regge model on GlueX data.
Quadratic WIMP-ALP coupling induces coherent freeze-out that allows WIMP annihilation cross sections up to 1000 times larger than standard while matching relic density, plus an ALP miracle where Planck-suppressed couplings naturally yield correct ALP dark matter abundance independent of initial mass
Chiral EFT predictions at N2LO for the tritium Gamow-Teller matrix element, with parameters fixed from scattering, overestimate the empirical value and indicate large higher-order corrections.
At m_pi ≈ 292 MeV, lattice QCD finds virtual-state poles, not bound states, in both the 3S1 and 1S0 nucleon-nucleon channels.
NuQuLib maps realistic nuclear Hamiltonians to qubit Hamiltonians and compares T-gate costs of QPE, QKrylov, and ODMD across valence and no-core model spaces.
Near-threshold structures in seven e+e- annihilation channels are simultaneously described by a single chiral-EFT N Nbar final-state interaction plus slowly varying short-distance sources, without channel-specific narrow resonances.
Within a restricted low-energy spin-sector ansatz for n-p scattering, direction-averaged magic is locally minimized at the CP-conserving point heta-bar=0 when the effective phase equals heta/4 or lies in specific windows.
Bootstrap consistency checks show that the NLO chiral EFT potential for the 1S0 two-nucleon wave remains valid over a significantly wider energy range than the LO version when compared to Granada phase shifts.
Develops stable minimum principles for scattering states with proven bounded errors from true states, enabling rigorous bounds on scattering amplitudes for momentum-dependent, Coulomb, and bound-state scattering.
Auxiliary counterterms provide exact cutoff independence in EFTs but encode no new physics and aid renormalization consistency and convergence.
The manifestly Lorentz-invariant chiral EFT potential at NLO, treated non-perturbatively, yields a reasonable description of low-energy NN phase shifts and deuteron properties.
Perturbative N3LO calculations in chiral EFT with RG-guided power counting yield robust predictions for light nuclei energies when calibrated on the tritium binding energy.
Chiral EFT derivation of the Δ⁻ → p e⁻ e⁻ amplitude including long-range neutrino loops, short-range counterterms, pion-mass dependence for collinear electrons, and a long-range prediction in the degenerate Δ-nucleon mass limit.
Varying neutron star core composition with hyperons and Delta resonances mildly affects the QCD axion mass limit from cooling, potentially bringing the DFSZ limit into the IAXO sensitivity window.
In the chiral confining model, in-medium nucleon mass evolution driven by scalar-field response and separation of confinement versus chiral effects governs repulsive three-body forces for saturation, alongside changes to internal energy and pressure distributions.
The DNN system forms a robust compact bound state in the I=1/2 (1^-) channel across cutoffs, while D*NN exhibits spin-dependent bound states in 0^-, 1^-, and 2^- channels with no resonances found.
Nonparametric GP-based high-density extensions yield softer EOS posteriors with larger uncertainties than parametric PP extensions when jointly constrained by multi-messenger neutron star observations.
Nuclei are 3A-quark systems where Fermi gas explains equal u/d quarks in light nuclei, a modified bag model fits heavier ones, and AdS5 duality predicts the lightest glueball's decay and sets the maximum stable nuclear charge at Z=82 for lead.
The MUSES Calliope engine computes multi-dimensional QCD equations of state, merges them consistently, and feeds them into viscous hydrodynamic simulations of heavy-ion collisions with movable critical points and critical scaling in transport coefficients.
After removing renormalization-scheme-dependent short-distance parts, the scrutinized three-nucleon forces yield small contributions to neutron and symmetric nuclear matter equations of state, aligning with standard chiral EFT expectations.
The universality assumption in the Koonin-Pratt formula for femtoscopic correlations introduces potentially large intrinsic uncertainty when extracting strong interactions between hadrons like nucleons.
This is a review chapter summarizing the established framework of scattering theory in particle physics.
