论文摘要
地面矢量$ b_ {c}^{\ ast} $梅森尚未实验发现。除了主要的电磁衰变外，非副电物弱衰减还为搜索神秘的$ b_ {c}^{\ ast} $ Mesons提供了另一种选择。受到$ b_ {c}^{\ ast} $梅森的潜在前景的启发，在未来的高亮度煤矿中，非副本$ b_ {c}^{\ ast} $弱衰变是通过底部和charm Quark衰减所引起的，并通过使用幼稚的因素化方法来研究。发现对于$ b_ {c}^{\ ast} $ $ {\ to} $ $ b_ {s，d}π$，$ b_ {s，d}^{\ ast}π$，$ b_ { $ b_ {s} k^{\ ast} $，$η_{c}（1s，2s）π$，$η_{c}（1s，2s）ρ$和$ψ（1s，2s，2s）π$衰减，甚至可以在Cepc，fcc-e和lhc和lhc中均可在Cepc和lhc中进行几百万种事件。
The ground vector $B_{c}^{\ast}$ meson has not yet been experimentally discovered until now. Besides the dominant electromagnetic decays, nonleptonic weak decays provide another choice to search for the mysterious $B_{c}^{\ast}$ mesons. Inspired by the potential prospects of $B_{c}^{\ast}$ mesons in future high-luminosity colliders, nonleptonic $B_{c}^{\ast}$ weak decays induced by bottom and charm quark decays are studied within the SM by using a naive factorization approach. It is found that for $B_{c}^{\ast}$ ${\to}$ $B_{s,d}π$, $B_{s,d}^{\ast}π$, $B_{s,d}ρ$, $B_{s}K$, $B_{s}^{\ast}K$, $B_{s}K^{\ast}$, $η_{c}(1S,2S)π$, $η_{c}(1S,2S)ρ$ and $ψ(1S,2S)π$ decays, a few hundred and even thousand of events might be observable in CEPC, FCC-ee and LHCb@HL-LHC experiments.
