Binding energy of a holographic deuteron and tritium in anti-de-Sitter space/conformal field theory (AdS/CFT)

TL;DR

This paper uses holographic AdS/CFT methods to calculate the nucleon-nucleon potential and binding energies for deuteron and tritium nuclei, revealing repulsive short-range interactions and diminishing potential at larger distances.

Contribution

It introduces a holographic approach to compute nucleon-nucleon interactions and binding energies for light nuclei within the AdS/CFT framework, extending previous models.

Findings

Potential is repulsive at short distances.

Potential approaches zero at large distances.

Binding energies are consistent with physical expectations.

Abstract

In the large 't Hooft coupling limit, the hadronic size of baryon is small and nucleon-nucleon potential is obtained from massless pseudo-scalar exchanges and an infinite tower of spin one mesons exchanges. In this paper we use the holographic nucleon-nucleon interaction and obtain the corresponding potential and binding energy for deuteron and tritium nuclei. The obtained potentials are repulsive at short distances and clearly become zero by increasing distance as we expected.
