Abstract The Coulomb-free 1 S 0 proton-proton (p-p) scattering length relies heavily on numerous and distinct theoretical techniques to remove the Coulomb contribution. Here, it has been determined from the half-off-the-energy-shell p-p scattering cr

The Hyperspherical Harmonics (HH) method is one of the most accurate techniques to solve the quantum mechanical problem for nuclear systems with a number of nucleons A ≤ 4. In particular, by applying the Rayleigh-Ritz or Kohn variational principle,

The energy per particle of symmetric nuclear matter and pure neutron matter is calculated using the many-body Brueckner–Hartree–Fock approach and employing the Chiral Next-to-next-to-next-to leading order (N3LO) nucleon–nucleon (NN) potential,

International audience; The Efimov window, or universal window, is a particular energy region in which few-body systems are loosely bound. Many characteristics of those systems are universal; their properties are largely independent of the particular

Light elements were produced in the first few minutes of the Universe through a sequence of nuclear reactions known as Big Bang nucleosynthesis (BBN)1,2. Among the light elements produced during BBN1,2, deuterium is an excellent indicator of cosmolog

We present a study of the effect of three-nucleon forces (3NFs) in (formula presented), (formula presented) and (formula presented) scattering at low energies. The used 3NF is derived from effective field theory at next-to-next-to-leading order. The

A bound-state variational method based on fully-antisymmetric hyperspherical harmonics and an hyperradial Lagrange mesh is presented and applied to the five-nucleon system with an effective nucleon-nucleon interaction, which artificially bounds this
