我们讨论了三体系统中奇异重子DNN和BNN的存在性,它们是没有夸克-反夸克对湮灭的真正奇异态。在考虑重夸克对称性的前提下,我们考虑了包含张量力的单玻色子交换势引起的DN − D <$N(BN − B <$N)混合。对于NN相互作用,采用阿贡v8势。通过对角化哈密顿量,我们得到了DNN和BNN系统中(I,JP)=(1/2,0-)的束缚态和(I,JP)=(1/2,1-)的共振态。
We discuss the existence of exotic dibaryons as DNN and BNN for three-body systems, which are genuine exotic states with no quark-antiquark pair annihilation. Respecting the heavy quark symmetry, we consider the DN − D∗N (BN − B∗N) mixing induced by the one boson exchange potential including the tensor force. For the NN interaction, the Argonne v8 potential is employed. By diagonalizing the Hamiltonian, we obtain bound states for (I, JP) = (1/2, 0−) and resonances for (I, JP) = (1/2, 1−) both in DNN and BNN systems.
