| 英文摘要 | We explore the existence of D Xi and D*Xi molecular states within the one boson exchange model. We regularize the potential derived in this model with a form factor and a cutoff of the order of 1 GeV. To determine the cutoff, we use the condition that the X(3872) is reproduced as a pole in the J(PC) = 1(++) D*(D) over bar amplitude. From this, we find that the J(P) = 1/2(-) D*Xi. system is on the verge of binding and has an unnaturally large scattering length. For the J(P) = 1/2(-) D Xi and the J(P) = 3/2(-) D*Xi systems, the attraction is not enough to form a bound state. From heavy quark symmetry and the quark model, we can extend the previous model to the P Xi(QQ) and P*Xi(QQ) systems, with P = B, D and Xi(QQ) = Xi(cc), Xi(bb). In this case, we predict a series of triply heavy pentaquarklike molecules. |
