论文摘要
最近，LHCB观察到了双重的Tetraquark候选人$ T_ {CC}^+$，并声称由于缺乏$ T_ {cc}^{++} $，因此其Isospin为零。但是，LHCB中$ t_ {cc}^{++} $的缺失可能是由于它们在$ pp $碰撞中的生产较低所致，因此仍然需要澄清$ t_ {cc}^+$的isospin。我们提出了一种从$ t_ {cc}^+\ d^+d^0π^0 $的$ t_ {cc}^+$研究的isospin属性的有效方法。该方法也可以应用于其他外来候选人。
Recently, LHCb observed a double-charmed tetraquark candidate $T_{cc}^+$ and claimed its isospin to be zero due to the absence of $T_{cc}^{++}$. However, the absence of the $T_{cc}^{++}$ in LHCb may be due to their low production in $pp$ collisions, thus the isospin of $T_{cc}^+$ still needs to be clarified. We propose an efficient way to investigate the isospin property of $T_{cc}^+$ from the Dalitz plot distribution of $T_{cc}^+\to D^+D^0π^0$. This method can also be applied to other exotic candidates.
