论文摘要
在这项研究中，我们研究了双链Tetraquarks $ t^{\ {cc \}} _ {[\ bar {q} \ bar {q}']} $的发现潜力。我们发现，他们在LHCB的生产横截面与$ \ sqrt {s} = 13 $ tev达到$ \ MATHCAL {O}（10^4）$ pb，这表明LHCB收集了$ \ Mathcal {O}（O}（O}（10^8）$。通过$ t^{\ {cc \}} _ {[\ bar { $ t^{\ {cc \}} _ {[\ bar {u} \ bar {d}]} \ to d^0d^{*+} \ to d^0d^0π^+$（如果不稳定），则非常期望他们在接近的将来会发现在LHCB。我们还讨论了未来Tera- $ Z $工厂的双链四夸克人的制作和衰落。
In this study, we investigate the discovery potential of double-charm tetraquarks $T^{\{cc\}}_{[\bar{q}\bar{q}']}$. We find that their production cross sections at the LHCb with $\sqrt{s} = 13$ TeV reach $\mathcal{O}(10^4)$ pb, which indicates that the LHCb has collected $\mathcal{O}(10^8)$ such particles. Through the decay channels of $T^{\{cc\}}_{[\bar{u}\bar{d}]}\to D^{+}K^{-}π^{+}$ or $D^0D^+γ$ (if stable) or $T^{\{cc\}}_{[\bar{u}\bar{d}]}\to D^0D^{*+}\to D^0D^0π^+$ (if unstable), it is highly expected that they get discovered at the LHCb in the near future. We also discuss the productions and decays of the double-charm tetraquarks at future Tera-$Z$ factories.
