Wei Han, Shi-Yuan Li, Yong-Hui Shang, Feng-Lan Shao, Tao Yao

摘要:

以$f_0(980)$为例,在夸克组合模型的框架下研究了奇异强子(多夸克态)产生的基本原理。计算并比较了在$\sqrt{s_{NN}}=200GeV$上Au+Au碰撞中$f_0(980)$分别作为$(s\bar s)$和$(s\bar q\bar s q)$的产生率和$p_T$谱。各种组合模型的幺正性,当开放的奇异强子的生产,解决。

英文摘要:

The philosophy on production of exotic hadrons (multi-quark states) in the framework of quark combination model is investigated, taking $f_0(980)$ as an example. The production rate and $p_T$ spectra of $f_0(980)$ considered as $(s\bar s)$ or $(s\bar q\bar s q)$ respectively, are calculated and compared in Au+Au collisions at $\sqrt{s_{NN}}=200GeV$. The unitarity of various combination models, when open for exotic hadron production, is addressed.
