文摘

We study the hadronic \(\bar{B}^0_s\) decays based on the existence of the resonant state \(f_J(2220)\) . In particular, we are able to explain the unexpected large experimental result of \(\mathcal{B}(\bar{B}^0_s\rightarrow J/\psi p\bar{p}) =(3.0^{+1.2}_{-1.1}\pm 0.52\pm 0.03)\times 10^{-6}\) measured recently by the LHCb collaboration due to the resonant contribution in \(\bar{B}^0_s\rightarrow J/\psi f_J(2220)\) with \(f_J(2220) \rightarrow p\bar{p}\) , while it is estimated to be at most of order \(10^{-9}\) in terms of the OZI rule without the resonance. In addition, we find that \(\mathcal{B}(\bar{B}^0_s\rightarrow D^{*0}(f_J\rightarrow ) p\bar{p})=(4.70\pm 2.89)\times 10^{-7}\) , \(\mathcal{B}(\bar{B}^0_s\rightarrow J/\psi (f_J\rightarrow )\pi \pi )=(15.6\pm 15.2)\times 10^{-6}\) , and \(\mathcal{B}(\bar{B}^0_s\rightarrow D^{*0}(f_J\rightarrow )\pi \pi )=(24.5\pm 24.4)\times 10^{-7}\) , while \(\mathcal{B}(\bar{B}^0_s\rightarrow J/\psi (f_J\rightarrow )K\bar{K}) and \(\mathcal{B}(\bar{B}^0_s\rightarrow D^{*0}(f_J\rightarrow )K\bar{K}) . Moreover, we predict that the decay branching ratios of \(\bar{B}^0_s\rightarrow (J/\psi ,D^{*0})\Lambda \bar{\Lambda }\) are \((2.68\pm 1.23)\times 10^{-7}\) and \((2.25\pm 0.80)\times 10^{-6}\) . Some of the predicted \(\bar{B}^0_s\) decays are accessible to the experiments at the LHCb.
