Pion absorption from the lowest atomic orbital in ²H, ³H, and ³He

NUCLEAR REACTIONS ²H(π^-, 2n), ³He(π^-, nd), (π^-, 2np), ³H(π^-, 3n), E at rest; calculated single and double differential absorption rates, total absorption rates. Calculations using chiral LO single-nucleon and two-nucleon transition operators with consistent initial and final nuclear states obtained with the chiral nucleon-nucleon SMS potential up to N4LO⁺ augmented by the consistently regularized chiral N2LO three-nucleon potential. Comparison with previous theoretical predictions and experimental data.

High-accuracy calculation of the deuteron charge and quadrupole form factors in chiral effective field theory

NUCLEAR STRUCTURE ²H; calculated proton and neutron form factors, isoscalar nucleon electric and magnetic form factors, deuteron charge and quadrupole form factors calculated at N⁴LO, deuteron structure radius squared and deuteron quadrupole moment predicted at N⁴LO in χEFT using two-nucleon potentials and charge-density operators derived in chiral effective field theory. Comparison with experimental data, and with Particle Data Group evaluations.

Low-energy theorems for nucleon-nucleon scattering at M_π = 450 MeV

NUCLEAR REACTIONS ¹H(n, n) at M_p=450 MeV; analyzed recent lattice QCD results for NN system obtained by the NPLQCD Collaboration; calculated neutron-proton phase shifts and the effective-range function for spin-triplet and spin-singlet channels, correlations between the inverse scattering length, effective range and the binding energy. Low-energy theorems (LET) for NN scattering along with the lattice-QCD results for the deuteron and dineutron binding energies from NPLQCD Collaboration.
