摘要
利用手征SU(3)夸克模型和推广的手征SU(3)夸克模型,在集团组态下研究了H粒子的结构,分析了两种不同的短程相互作用机制即矢量介子交换效应和单胶子交换效应、不同的禁闭势、耦合道及标量介子混合角等因素对H粒子结合能的影响.研究表明,准确的实验信息将有助于检验理论模型,决定如何选取禁闭势和是否需要考虑标量介子混合角等问题.
We investigate the structure of H particle within the framework of chiral SU(3) quark model and the extended chiral SU(3) quark model.Firstly,the different mechanisms of short-range interactions,vector exchange or one-gluon exchange,are analyzed.Secondly,the different confinement potentials and channel-coupling effects are studied.Finally,the effects of the mixing of scalar mesons on the H particle are investigated.The results show that the further exact information from experiments will be helpful in deciding the different confinement potentials and the mixing of scalar mesons in our models.
