Abstract
- We study the Zcs(3985) and Zcs(4000) exotic states in the decays of Λb baryons through a molecular scenario. In the final state interaction, the Λb→Λc+Ds(⁎)− decays are followed by the Λc+Ds(⁎)− to Zcs−p rescatterings via exchange of a D(⁎) meson. We predict a branching fraction of (3.1−2.6+1.4)×10−4 for Λb→Zcs−p, which can be measured in the Λb→J/ψK(⁎)−p decay. This study proposes a new approach to test the molecular model, and guides future experimental searches for the Zcs(3985) and Zcs(4000).
