Zcs (3985)- : A strange hidden-charm tetraquark resonance or not?

Inspired by the newly Z(cs) (3985)(-) reported by the BESIII Collaboration in the K+ recoil-mass spectrum of the of e(+) e(-) -> (D*D-0(s)-/(DDs)-D-0*(-))K+ processes, we perform a dynamical study on the D-(*()0)Ds*(-) interactions by adopting a one-boson-exchange model and considering the coupled channel effect. After producing the phase shifts for all the discussed channels, our results exclude the newly Z(sc)(3985)(-) as a D*D-0(s)-/(DDs)-D-0*(-)/D*D-0(s)*(-) resonance with I(J(P)) = 1/2(1(+),0(-), 1(-), 2(-)).

Automated summary

In this study, a dynamical analysis on the D-(*()0)Ds*(-) interactions was performed using a one-boson-exchange model and considering the coupled channel effect. The results obtained from producing phase shifts for all discussed channels excluded the newly reported Z(sc)(3985)(-) as a resonance with specific quantum numbers.
