| contents | In this work we investigate the decay and production properties of the strange double-charm pentaquark $P_{ccs}^{++}$ with strangeness $S=-1$. Building upon our previous work predicting its $J^P=1/2^-$ molecular configuration, we employ three-point QCD sum rules to calculate its strong decay widths and estimate its production branching ratio via $Ξ_{bc}^+$ baryon decays. The total strong decay width to the $Ξ_{cc}\bar{K}$ and $Ω_{cc}π$ final-state channels is determined as $85\pm19$ MeV. Furthermore, using a rescattering mechanism, we analyze the $Ξ_{bc}^+\rightarrow D_s^{\ast-}Ξ_{cc}^{++}\rightarrow D^-P_{ccs}^{++}$ process and estimate the production branching ratio to be $\mathcal{B}r(Ξ_{bc}^+\rightarrow D^-P_{ccs}^{++})=(4.3_{-1.5}^{+2.0})\times10^{-6}$. The relatively narrow width and detectable branching ratio suggest the possibility searching for this pentaquark state in the future. |
