The Effects of Different Kinds of Confinements and Configuration Space on N、Δ Spectra

  • In this paper,the confinement potential with colour screening effect as well as the mixing of configuration space,the basis functions with different size parameter b and the vector coupling component of confining potential have been considered to study the N、Δ spectra.The results show that these effects can improve theoretical calculations and give a more reasonable and better description for N、Δ systems.

Abstract: In this paper,the confinement potential with colour screening effect as well as the mixing of configuration space,the basis functions with different size parameter b and the vector coupling component of confining potential have been considered to study the N、Δ spectra.The results show that these effects can improve theoretical calculations and give a more reasonable and better description for N、Δ systems.
