Contribution

It introduces a vector diquark approach combined with Hartree-Fock interactions and tunneling methods to analyze multiquark states' masses and decay widths.

Findings

Abstract

By using of vector diquark ideas in the chiral limit diquark correlations in the relativistic region and imposing HF interactions between quarks in a vector diquark we calculated the mass of two multiquark states (Theta pentaquark and H dibaryon), also by using of tunneling method we simultaneously calculated their decay width
