摘要:

使用托马斯-费米夸克模型,创建了集体的、球对称的态密度,以代表零温度下具有各种简并度的相互作用费米子气体。在一个多五夸克族上,对所有可能的组态进行平均后,得到了色相互作用几率。结果发现,三种不同的夸克费米函数是必要的光,粲,反粲夸克。这些被假定为线性相关的比例常数导致一致性条件。我们分析了这些条件,发现它们导致一个有趣的模式的球夸克分布。

英文摘要:

Using the Thomas-Fermi quark model, a collective, spherically symmetric density of states is created to represent a gas of interacting fermions with various degeneracies at zero temperature. Over a family of multi-pentaquarks, color interaction probabilities are obtained after averaging over all the possible configurations. It is found that three different Thomas-Fermi functions are necessary for light, charm, and anti-charm quarks. These are assumed to be linearly related by proportionality constants resulting in consistency conditions. We analyze these conditions and find that they lead to an interesting pattern of spherical quark distributions.
