摘要:

在耦合道么正方法和局域隐规范方法的框架下,研究了各种粲介子和粲重子之间的相互作用。预言了几个质量大于4GeV、宽度小于100 MeV的介子-重子动力学产生的窄$N^*$和$Λ^*$共振态。预测的新共振绝对不能容纳由三个组成夸克的夸克模型,可以在即将到来的PANDA/FAIR实验中寻找。

英文摘要:

The interaction between various charmed mesons and charmed baryons are studied within the framework of the coupled channel unitary approach with the local hidden gauge formalism. Several meson-baryon dynamically generated narrow $N^*$ and $Λ^*$ resonances with hidden charm are predicted with mass above 4 GeV and width smaller than 100 MeV. The predicted new resonances definitely cannot be accommodated by quark models with three constituent quarks and can be looked for at the forthcoming PANDA/FAIR experiments.
