在夸克模型中对$X$(3915)分子$D^*\bar{D^*}$态的动力学研究

Dynamical study of the $X$(3915) as a molecular $D^*\bar{D^*}$ state in a quark model

Youchang Yang, Jialun Ping

摘要:

考虑到$1 \otimes 1$和$8 \otimes 8$的色结构耦合,在Bhaduri,Cohler和Nogami夸克模型下,用高斯展开法计算了新观测到的$X$(3915)作为$S-$波$D^*\bar{D^*}$态的能量.由于颜色耦合,发现了$D^*\bar{D^*}$与$J^{PC}=0^{++}$的结合态,这与$X$(3915)的实验数据符合得很好.本文还预测了$B^*\bar{B^*}$与$J^{PC}=0^{++}$和$2^{++}$的结合态。

英文摘要:

Considering the coupling of color $1 \otimes 1$ and $8 \otimes 8$ structures, we calculate the energy of the newly observed $X$(3915) as $S-$wave $D^*\bar{D^*}$ state in the Bhaduri, Cohler, and Nogami quark model by the Gaussian Expansion Method. Due to the color coupling, the bound state of $D^*\bar{D^*}$ with $J^{PC}=0^{++}$ is found, which is well consonant with the experimental data of the $X$(3915). The bound state of $B^*\bar{B^*}$ with $J^{PC}=0^{++}$ and $2^{++}$ are also predicted in this work.
