论文摘要
我们对$ cc \ bar c \ bar c $ tetraquarks的衰减进行定量分析，并用$ j^{pc} = 0^{++}，2^{++} $进入4个muons，并进入隐藏和开放的脑膜中，并首次进入隐藏的和开放式的ersons and Istimate，这是第一次充满迷人的tetraquark deTail deTail deDay width。计算出的横截面上限为4个MUONS通道的$ \ sim 40 $ fb，$ \ sim 28 $ nb用于$ d^{（*）} \ bar d^{（*）} \ toeμ$ channel。根据我们的结果，使用当前的灵敏度LHCB应检测两个信号，价格为$ 0^{++} $和$ 2^{++} $完全掌握的Tetraquarks。
We perform a quantitative analysis of the decays of $cc\bar c\bar c$ tetraquarks with $J^{PC}=0^{++}, 2^{++}$ into 4 muons and into hidden- and open-charm mesons and estimate, for the first time, the fully charmed tetraquark decay width. The calculated cross section upper limit is $\sim 40$ fb for the 4 muons channel, and $\sim 28$ nb for the $D^{(*)} \bar D^{(*)} \to eμ$ channel. On the basis of our results, with the present sensitivity LHCb should detect both signals, for $0^{++}$ and $2^{++}$ fully-charmed tetraquarks.
