具有奇异电荷的强子共振

Hadronic resonances with exotic electric charge

G. De Conto, V. Pleitez

摘要:

考虑到电荷为5/3的夸克和某些3-3-1模型预测的$-4/3$(单位为$\vert e\vert$),我们对介子和重子的长寿命共振进行了分类.这些奇特的共振态中,有些具有通常的电荷$0,\pm1$,有些具有$\pm(3,4,5)$,而最轻的共振态只衰减成轻子加上已知的共振态。我们提出了另一种重的$SU(3)_H$整体对称性,在这种对称性下可以构造出只包含奇异夸克的强子。

英文摘要:

We classify the meson and baryon long lived resonances considering quarks with electric charge 5/3 and $-4/3$ (in units of $\vert e\vert$) predicted by some 3-3-1 models. Some of these exotic resonances have the usual electric charges $0,\pm1$, others have $\pm(3,4,5)$, and the lightest ones decaying only into leptons plus known resonances. We propose another heavy $SU(3)_H$ global symmetry under which hadrons involving only exotic quarks can be constructed.
