在单玻色子交换模型中，我们研究了双粲重子[Xi(cc)(3621)]和粲介子（D和D*）的分子态。我们的模型表明存在两种可能的三粲分子五夸克，一种是I(J(P)) = 0（1/2(-)）的Xi D-cc态，另一种是I(J(P)) = 0（3/2(-)）的Xi D-cc*态，我们没有找到等三重态的束缚解。此外，我们还扩展了我们的公式来探索Xi(cc)(B) / baro(()*()), Xi(cc)(D) / bar(（)*()）和Xi B-cc(（)*()）状态，其中I(J(P)) = 0(3/2(-))，并且我们没有找到等三重态的界解。此外，我们还扩展了我们的公式来探索Xi(cc)(B) / bar (()*()), Xi(cc)(D) / bar(（)*()）和Xi B-cc(（)*()）体系，并找到更多可能的重味分子五夸克，Xi(cc)(B) / bar状态，I(J(P)) = 0(1/2(-)), Xi(cc)(B) / bar*状态，I(J(P)) = 0(3/2(-)), Xi(cc)(D) / bar*/Xi B-cc*状态，I(J(P)) = 0（1/2(-)）。鼓励对这些预测的三粲分子五夸克进行实验研究。
In a one-boson-exchange model, we study molecular states of double-charm baryon [Xi(cc)(3621)] and a charmed meson (D and D*). Our model indicates that there exist two possible triple-charm molecular pentaquarks, a Xi D-cc state with I(J(P)) = 0(1/2(-)), and a Xi D-cc* state with I(J(P)) = 0(3/2(-)), and we do not find bound solutions for isotriplet states. In addition, we also extend our formula to explore Xi(cc) (B) over baro(()*()), Xi(cc)(D) over bar (()*()), and Xi B-cc(()*()) state with I(J(P)) = 0(3/2(-)), and we do not find bound solutions for isotriplet states. In addition, we also extend our formula to explore Xi(cc)(B) over bar (()*()), Xi(cc)(D) over bar (()*()), and Xi B-cc(()*()) systems and find more possible heavy flavor molecular pentaquarks, a Xi(cc)(B) over bar state with I(J(P)) = 0(1/2(-)), a Xi(cc)(B) over bar* state with I(J(P)) = 0(3/2(-)), and Xi(cc)(D) over bar*/Xi B-cc* states with I(J(P)) = 0(1/2(-)). Experimental research for these predicted triple- charm molecular pentaquarks is encouraged.
