论文摘要
我们对$ \ bark吻*$,$ηΩ$($ s $ -wave)和$ \ bark吻$($ d $ - 波)频道的相互作用进行了研究,其中从Chiral lagral lagral lagral lagral lagral lagral lagral lagral lagral lagral lagral lagral lagral in chirlangians中获得了$ \ bar k k k k k k k erk k k k a $ \ bar k k k k k k ak $ $ \ bar k k k k k a的过渡潜力。 $ \ bar kk吻^*$,$ηΩ$和$ \ bark吻$之间的过渡电位是根据自由参数占据的,该参数与截断一起将Meson-Baryon Loops的正规化拟合到$ω(2012)$数据。我们发现,包括$γ_{ω^* \ toπ\ bar kk吻}/γ_{ω^* \ to \ bar kk吻} $上的所有数据,包括与这些通道中的中孔baryon相互作用的分子图片兼容。
We conduct a study of the interaction of the $\bar K Ξ^*$, $ηΩ$($s$-wave) and $\bar K Ξ$($d$-wave) channels within a coupled channel unitary approach where the transition potential between the $\bar K Ξ^*$ and $ηΩ$ channels is obtained from chiral Lagrangians. The transition potential between $\bar K Ξ^*$, $ηΩ$ and $\bar K Ξ$ is taken in terms of free parameters, which together with a cut off to regularize the meson-baryon loops are fitted to the $Ω(2012)$ data. We find that all data including the recent Belle experiment on $Γ_{Ω^* \to π\bar K Ξ}/ Γ_{Ω^* \to \bar K Ξ}$, are compatible with the molecular picture stemming from meson baryon interaction of these channels.
