  "abstract": "In this work, we study the unquenched effects on the low-lying $Ω_b(1P)$ states with a coupled-channel equations. We reveal how the unquenched effects affect the $Ω_b(1P)$ spectroscopy and component mixing. The numerical results indicate that the $J^P=1/2^-$ $Ω_b(1P)$ state dominated by the $j_\\ell=0$ configuration exhibits significant coupled-channel effects due to its $S$-wave coupling to the $Ξ_b\\bar{K}$ channel, where $j_\\ell$ denotes the total angular momentum of the light flavor degrees-of-freedom. In this scenario, the mass of this state may be shifted close to or below the $Ξ_b\\bar{K}$ threshold, making the radiative and isospin-breaking channels kinematically allowed decay processes. The present analysis provides a coupled-channel perspective on the low-lying $Ω_b(1P)$ spectrum and offers guidance for future experimental studies of excited bottom baryons.",
