论文摘要
我们通过使用固定的中心近似与Faddeev方程式搜索三个车身系统的界面，研究了两个$ d^* $和$ \ bar {k}^{*} $的相互作用。由于$ d^* d^* $相互作用很有吸引力并且具有界限，因此$ d^* \ bar {k}^{*} $相互作用的情况也是如此，其中$ j^{p} = 0^{+} $ bongationd bound状态与$ x_0（2900（2900）$ dotility nests $ nests $ nests $}用$ ccs $ open夸克绑定了状态。我们获得Isospin $ i = 1/2 $的界面状态，负奇偶校验和总旋转$ j = 0,1,2 $。对于$ j = 0 $，我们获得一个状态，对于$ j = 1,2 $，我们在每种情况下都会获得两个状态。绑定能量从$ 56 $ MEV到$ 151 $ MEV，宽度从$ 80 $ MEV到$ 100 MEV。
We study the interaction of two $ D^* $ and a $\bar{K}^{*}$ by using the Fixed Center Approximation to the Faddeev equations to search for bound states of the three body system. Since the $ D^* D^* $ interaction is attractive and gives a bound state, and so is the case of the $D^* \bar{K}^{*}$ interaction, where the $J^{P}=0^{+}$ bound state is identified with the $X_0 (2900)$, the $ D^* D^* \bar{K}^{*}$ system leads to manifestly exotic bound states with $ccs$ open quarks. We obtain bound states of isospin $I=1/2$, negative parity and total spin $J=0,1,2$. For $J=0$ we obtain one state, and for $J=1,2$ we obtain two states in each case. The binding energies range from $56$ MeV to $151$ MeV and the widths from $80$ MeV to $100$ MeV.
