Abstract

In this work, we study the diquark-diquark-antiquark type uuscc pentaquark states in the light-flavor 10 representation via the QCD sum rules in details. We exhaust the lowest five-quark configurations and obtain the spectroscopy of the uuscc pentaquark states with the quantum numbers IJ^P=1(1)/(2)^-, 1(3)/(2)^-, 1(5)/(2)^-, and suggest to investigate them in the decay chain Σ_b⁺→ P_cs⁺ ϕ→ J/ψΣ^*+ ϕ experimentally.
