耦合夸克自由度的强子-强子势用于研究X(3872)

Hadron-hadron potentials coupled to quark degrees of freedom for X(3872)

Ibuki Terashima, Tetsuo Hyodo

AI总结:

本研究针对奇特强子X(3872)的内部结构,构建耦合夸克道的强子-强子势,研究D^0\bar{D}^{*0}势性质,并通过散射相移对比多种局域近似。

摘要:

为研究奇特强子X(3872)的内部结构,考虑夸克与强子间的耦合道势十分必要,因为X(3872)被视为c\bar{c}与D^0\bar{D}^{*0}的混合态。本工作构建了耦合夸克道的强子-强子势,研究了对应X(3872)的D^0\bar{D}^{*0}势的性质,尤其聚焦散射相移对比了多种局域近似。

英文摘要:

To study the internal structure of the exotic hadron $X(3872)$, considering the coupled-channel potential between quarks and hadrons is necessary because $X(3872)$ is regarded as a mixture state of $c\bar{c}$ and $D^0\bar{D}^{*0}$. In this work, we construct the hadron-hadron potentials coupled to the quark channel and study the properties of the $D^0\bar{D}^{*0}$ potentials for $X(3872)$. In particular, we compare various local approximations by focusing on the scattering phase shifts.
