摘要
为解决超子疑难,在夸克模型框架下研究了超子物质的三体力.作为解决这个疑难所需的额外排斥效应的候选者,关注由夸克泡利效应和色磁作用引起的排斥芯.结果表明,在∧NN系统最小阈值处,不存在明显的排斥芯结构,但色磁作用提供了强烈的三体排斥效应.
Abstract
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.
