论文摘要
在过去的20年中，大多数异国情调的隐藏障碍者都发现，如果假设存在夸克的第七个味道，则在正常的介子和重子中发现了整齐地融入夸克模型。为了使夸克复制异国载体的光谱（质量，旋转，奇偶校验），它必须具有$ \ sim $ 2.9 GEV的质量和$ - \ tfrac {1} {3} $的费用。这些黑龙的观察到的产生和衰减模式可以由一个模型复制，该模型还包括一个与夸克相互作用但与任何仪表玻色子相互作用的光标量。
Most of the exotic hidden-charm hadrons discovered over the last 20 years fit neatly into the quark model as normal mesons and baryons if the existence of a seventh flavor of quark is hypothesized. For the quark to reproduce the spectrum (mass, spin, parity) of exotic hadrons, it would have to have a mass of $\sim$2.9 GeV and a charge of $-\tfrac{1}{3}$. The observed production and decay modes of these hadrons can be reproduced by a model that also includes a light scalar that interacts with quarks but not with any gauge bosons.
