Decay and production properties of a strange double-charm pentaquark

In this work, we investigate the decay and production properties of the strange double-charm pentaquark P c c s + + 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 b c + baryon decays. The total strong decay width to the Ξ c c K ¯ and Ω c c π final-state channels is determined as 85 ± 19 MeV . Furthermore, using a rescattering mechanism, we analyze the Ξ b c + → D s * − Ξ c c + + → D − P c c s + + process and estimate the production branching ratio to be B r ( Ξ b c + → D − P c c s + + ) = ( 4.3 − 1.5 + 2.0 ) × 10 − 6 . The relatively narrow width and detectable branching ratio suggest the possibility searching for this pentaquark state in the future.
