Study of Three-Baryon Systems in a Quark Model for Solution of Hyperon Puzzle
We evaluate the three-body baryon effect in the quark model to solve the hyperon puzzle.As candidates for the extra repulsive effect required to solve the puzzle,we focus on the structural repulsive core caused by the quark-Pauli effect and the color-magnetic term.The result is that in the lowest threshold ∧NN system,no signific-ant structural repulsive core is obtained,but a strong repulsive three-body effect is obtained from the color-magnetic term.
