摘要:

在这项工作中,我们调查的可能性,形成的状态,从涉及的$D^*D^*D^*$系统的动力学考虑,两个$D^*$的产生一个$J^P=1^+$束缚态,与同位旋0,这已经在早期的理论工作中预测。我们在固定中心近似下求解了该系统的Faddeev方程,发现了具有粲$3$,同位旋$1/2$,质量$\sim 6000$ MeV的$J^P=0^-$,$1^-$和$2^-$态的存在,它们是明显的奇异强子,即,多夸克的内部结构

英文摘要:

In this work we investigate the possibility of the formation of states from the dynamics involved in the $D^*D^*D^*$ system by considering that two $D^*$'s generate a $J^P=1^+$ bound state, with isospin 0, which has been predicted in an earlier theoretical work. We solve the Faddeev equations for this system within the fixed center approximation and find the existence of $J^P=0^-$, $1^-$ and $2^-$ states with charm $3$, isospin $1/2$, masses $\sim 6000$ MeV, which are manifestly exotic hadrons, i.e., with a multiquark inner structure.
