Nucleon-nucleon potential: Drift effects

Nucleon-Nucleon Potential from Holography

In the holographic model of QCD, baryons are chiral solitons sourced by D4 flavor instantons in bulk of size 1/ √ λ with λ = gNc. Using the ADHM construction we explicit the exact two-instanton solution in bulk. We use it to construct the core NN potential to order Nc/λ. The core sources meson fields to order √ Nc/λ which are shown to contribute to the NN interaction to order Nc/λ. In holograph...

Holographic Deuteron and Nucleon-Nucleon Potential

We compute the potential between a pair of nucleons in the D4-D8 holographic QCD. In the large ’t Hooft coupling limit, λ ≫ 1, the hadronic size of the baryon is small ∼ 1/ √ λMKK , and their interaction with mesons are well approximated by a set of dimension four and five operators. The nucleon-nucleon potential emerges from one-boson exchange picture involving massless pseudo-scalars and an i...

Nucleon-nucleon scattering in a harmonic potential

The discrete energy-eigenvalues of two nucleons interacting with a finite-range nuclear force and confined to a harmonic potential are used to numerically reconstruct the free-space scattering phase shifts. The extracted phase shifts are compared to those obtained from the exact continuum scattering solution and agree within the uncertainties of the calculations. Our results suggest that it mig...

Low momentum nucleon-nucleon potential and shell model effective interactions

A low momentum nucleon-nucleon (NN) potential Vlow−k is derived from meson exhange potentials by integrating out the model dependent high momentum modes of VNN . The smooth and approximately unique Vlow−k is used as input for shell model calculations instead of the usual Brueckner G matrix. Such an approach eliminates the nuclear mass dependence of the input interaction one finds in the G matri...
