分析了和的质谱和强衰变。我们的结果表明，和是两个不同的共振。较窄的似乎是一个很好的混合候选人。我们支持夸克偶素。建议今后在和的通道中寻找同位旋伙伴。后一种渠道对于测试混合场景非常重要。
The mass spectrum and strong decays of the and are analyzed. Our results indicate that and are the two different resonances. The narrower seems likely a good hybrid candidate. We support the as the quarkonium. We suggest to search the isospin partner of in the channels of and in the future. The latter channel is very important for testing the hybrid scenario.
