论文摘要
$ξ_b（6227）$ baryon带有量子号$ j^p = 1/2^{ - } $被认为是由$σ_b$ baryon和$ \ bar {k} $ Meson组成的分子状态。 $σ_b\ bar {k} $分子状态的部分衰减宽度借助有效的lagrangians的帮助，将通过HADRONIC LOOPS评估。 $ξ_b（6227）\toγB$和$ξ_b（6227）\toγξ^{'} _ b $的部分宽度分别为1.50-1.02 keV和17.56-24.91 keV，分别可用于LHCB。根据我们的结果，我们认为对$ξ_b（6227）$的辐射衰减宽度的实验确定对于理解其内在特性很重要。
The $Ξ_b(6227)$ baryon with the quantum number $J^P=1/2^{-}$ is considered as a molecular state composed of a $Σ_b$ baryon and $\bar{K}$ meson. The partial decay widths of the $Σ_b\bar{K}$ molecular state into $Ξ_bγ$ and $Ξ_b^{'}γ$ final states through hadronic loops are evaluated with the help of the effective Lagrangians. The partial widths for the $Ξ_b(6227)\toγΞ_b$ and $Ξ_b(6227)\toγΞ^{'}_b$ are evaluated to be about 1.50-1.02 KeV and 17.56-24.91 KeV, respectively, which may be accessible for the LHCb. Based on our results we argue that an experimental determination of the radiative decay width of $Ξ_b(6227)$ is important for the understanding of its intrinsic properties.
