论文摘要
我们通过包括具有异国量子数量的低层混合非ET $ j^{pc} = 1^{ - +} $，并使用$ j^{pc} = 1^{+ - $ - $ - $ - $ - $ - $（3）$（3）$（3）$（3）$（3）$（3）$（3）$（3）手性对称性。我们将$π_1^{hyb} =π_1（1600）$的分配作为输入来确定未知参数。然后，我们计算最轻的载体和伪型混合质量，可以指导正在进行的和即将进行的实验来寻找杂种。
We enlarge the chiral model, the so-called extended Linear Sigma Model (eLSM), by including the low-lying hybrid nonet with exotic quantum numbers $J^{PC}=1^{-+}$ and the nonet of their chiral partners with $J^{PC}=1^{+-}$ to a global $U(3)_r \times U(3)_l$ chiral symmetry. We use the assignment of the $π_1^{hyb}= π_1(1600)$ as input to determine the unknown parameters. Then, we compute the lightest vector and pseudovector hybrid masses that could guide ongoing and upcoming experiments in searching for hybrids.
