类底介子的非绝热描述
Diabatic description of bottomoniumlike mesons
摘要：
我们应用非绝热方法，特别适合于基于QCD的常规（夸克-反夸克）和非常规（夸克-反夸克+介子-介子）介子态的研究，隐藏的底部介子的描述。进行了质量高达约$10.8$ GeV的$I=0$、$J^{++}$和$1^{--}$共振的光谱分析。所有实验上已知的共振态，包括常规态和非常规态的质量和宽度都可以很好地再现。特别是，我们预测一个显着的$B\bar{B}^{\ast}$组件在$Υ(10580)$。我们还预言了一个尚未发现的非常规$1^{++}$窄态的存在，它具有显著的$B_{s}\bar{B}_{s}^{\ast}$含量，使其衰变为$Υ(1S)ϕ$，其实验发现将为我们的理论分析提供一定的支持.
英文摘要：
We apply the diabatic approach, specially suited for a QCD based study of conventional (quark-antiquark) and unconventional (quark-antiquark + meson-meson) meson states, to the description of hidden-bottom mesons. A spectral analysis of the $I=0$, $J^{++}$ and $1^{--}$ resonances with masses up to about $10.8$ GeV is carried out. Masses and widths of all the experimentally known resonances, including conventional and unconventional states, can be well reproduced. In particular, we predict a significant $B\bar{B}^{\ast}$ component in $Υ(10580)$. We also predict the existence of a not yet discovered unconventional $1^{++}$ narrow state, with a significant $B_{s}\bar{B}_{s}^{\ast}$ content making it to decay into $Υ(1S)ϕ$, whose experimental discovery would provide definite support to our theoretical analysis.
