地球现象学与相对论性通量管模型

Glueball phenomenology and the relativistic flux tube model

Fabien Buisseret, Vincent Mathieu, Claude Semay

摘要:

相对论性通量管模型是描述受限夸克和胶子的一种有效方法,其中受限相互作用由通量管(一种南部-后藤弦)来进行。我们首先表明,相对论通量管模型可以适用于胶球看作横向组分胶子的束缚态。经过比较的方法与通常的无自旋Salpeter哈密顿,我们计算胶球质量和衰变宽度。最后对$η$ - $η'$ -pseudosclar胶球问题、胶球-Pomeron猜想和有限温度效应作了评述。我们还指出了胶球的开放和封闭的通量管模型之间的二元性的存在。

英文摘要:

The relativistic flux tube model is an effective description of confined quarks and gluons in which the confining interaction is carried by the flux tube, a Nambu-Goto string. We first show that the relativistic flux tube model can be applied to glueballs seen as bound states of transverse constituent gluons. After a comparison of that approach with usual spinless Salpeter Hamiltonians, we compute glueball masses and decay widths. Comments about the $η$-$η'$-pseudosclar glueball problem, the glueball--Pomeron conjecture, and finite-temperature effects are finally given. We also point out the existence of a duality between open- and closed-flux tube models of glueballs.
