论文摘要
在对充电和中性$ z_c（3900）$进行实验性观察之后，追求这些异国情调状态的其他生产模式至关重要。在这项工作中，我们调查了通过LHCB的B-Baryons衰减来研究$ Z_C（3900）$的可能性。针对各种过程的衰减幅度已通过SU（3）不可还原的非扰动幅度进行了参数化。从这些结果中得出了部分衰减宽度的许多关系。 $λ_b^0 \toλ^0 z_c^0（3900）$，$ξ_b^ - \ t toσ^ - z_ {c}^0（3900）$和$ξ_b^0 \λ^0 Z_________ {C}^0（3900）$的衰减宽度的衰减宽度的衰减宽度。 估计的。本文介绍的结果可以在将来在强子墙面实验测试。
After the experimental observation of charged and neutral $Z_c(3900)$, it is of prime importance to pursue searches for additional production modes of these exotic states. In this work, we investigate the possibility to study the $Z_c(3900)$ through weak decays of b-baryons at the LHCb. Decay amplitudes for various processes have been parametrized in terms of the SU(3) irreducible nonperturbative amplitudes. A number of relations for the partial decay widths are deduced from these results. The decay widths of $Λ_b^0\to Λ^0 Z_c^0(3900)$, $Ξ_b^- \to Σ^- Z_{c}^0(3900)$ and $Ξ_b^0 \to Λ^0 Z_{c}^0(3900)$ have also been calculated from which some relevant partial decay widths of b-baryons could be estimated. The results presented in this paper can be tested experimentally at hadron colliders in the future.
