Strong decays of the Pcs(4459) as a $$\Xi_{c}\bar{D}^{\ast}$$ molecule

In this work, we study the strong decay of newly observed Pcs(4459), assuming that it is a pure $$\Xi_{c}\bar{D}^{\ast}$$ molecular state. Considering two possible spin-parity assignments JP = 1/2− and 3/2−, partial widths state into J/ψΛ, D − Λ + , $$\bar{D}\Xi_{c}^{(\prime)}$$ final states through hadronic loops are evaluated with help effective Lagrangians. comparison LHCb data, S-wave $$\bar{D}^{\ast}\Xi_{c}$$ assignment for Pcs(4459) supported by our study, while in 3/2− case may be explained as an coupled bound lager component. addition, calculated picture indicate allowed mode, $$\bar{D}^{\ast}\Xi_{c}^{\prime}$$ have biggest branching ratio. The experimental measurements process could crucial test molecule interpretation Pcs(4459).
