格点量子色动力学静-静-光-光势的底偶素共振

Bottomonium resonances from lattice QCD static-static-light-light potentials

Lasse Mueller, Pedro Bicudo, Nuno Cardoso, Marc Wagner

摘要:

我们利用格点量子色动力学的静-静-光-光势研究了$I=0$夸克偶素共振衰变成重-轻介子对的过程。为此,我们解决了耦合通道薛定谔方程的限制夸克偶素通道和通道的重轻介子对计算相移和$\mbox{T}$矩阵极点的最轻的衰变通道。我们讨论了我们的结果$S$,$P$,$D$和$F$波态的背景下,相应的实验结果,特别是$Υ(10753)$和$Υ(10860)$。

英文摘要:

We study $I=0$ quarkonium resonances decaying into pairs of heavy-light mesons using static-static-light-light potentials from lattice QCD. To this end, we solve a coupled channel Schrödinger equation with a confined quarkonium channel and channels with a heavy-light meson pair to compute phase shifts and $\mbox{T}$ matrix poles for the lightest decay channel. We discuss our results for $S$, $P$, $D$ and $F$ wave states in the context of corresponding experimental results, in particular for $Υ(10753)$ and $Υ(10860)$.
