Study of the ground-state energies of some nuclei using hybrid model (Q2244196)

Summary: The quark-quark (QQ) interaction as a perturbed term to the nucleon-nucleon interaction (NN) without any coupling between them is studied in a hybrid model. This model is used to calculate the ground-state energies of \(^2 \mathrm{H}_1\) and \(^4 \mathrm{He}_2\) nuclei. In a semirelativistic framework, this model is encouraged for light nuclei and the instanton-induced interaction by using the QQ potential and the NN interaction for a small scale around the hadron boundaries. This hybrid model depends on two theories, the one-boson exchange potential (OBEP) and the Cornell-dressed potential (CDP) for QQ. A small effect of quark-quark interaction is obtained on the values of the ground-state energies, around 6.7 and 1.2 percentage for \(^2 \mathrm{H}_1\) and \(^4 \mathrm{He}_2\), respectively nuclei.
