Investigation of the bottom analog of the Zcs(3985) state

TL;DR

This study investigates the potential existence of strange hidden bottom tetraquark states using quark models, predicting several resonance states that could be observed in future experiments, despite no bound states being found.

Contribution

The paper provides the first theoretical predictions of resonance states for the bottom analog of the Zcs(3985) using two quark models, considering both meson-meson and diquark-antidiquark configurations.

Findings

No bound states found in both models.

Predicted resonance states with specific energy ranges and quantum numbers.

Accessible for future experimental verification at LHCb.

Abstract

Motivated by the recent discovery of the hidden charm exotic state with strangeness by the BESIII and LHCb Collaborations, we study the $S$ wave strange hidden bottom tetraquark in two kinds of quark models. Both meson-meson and diquark-antidiquark configurations are taken into account. The numerical results indicate that there is no bound state in both quark models. However, several resonance states have been predicted. Three resonance states with $I(J^{P})=\frac{1}{2}(0^{+})$ are found, the energy ranges of which are $10479\sim 10550$, $10528\sim 10632$, and $10597\sim 10681$ MeV, respectively. Three resonance states with $I(J^{P})=\frac{1}{2}(1^{+})$ are predicted to be located in $10491\sim 10675$, $10502\sim 10679$, and $10522\sim 10723$ MeV, respectively. Moreover, there also exist a resonance with $I(J^{P})=\frac{1}{2}(2^{+})$ and the mass is estimated to be $10531\sim 10680$ MeV. All these predicted states in the present work should be accessible for the further experiments in LHCb
