英文摘要 | We perform a coupled-channel study of the possible deuteron-like molecules with two heavy flavor quarks, including the systems of D-(*D-)(()*()) with double charm, (B) over bar (()*())(B) over bar (()*()) with double bottom, and D-(*())(B) over bar (()*()) with both charm and bottom, within the one-boson-exchange potential model. In our study, we take into account the S-D mixing which plays an important role in the formation of the loosely bound deuteron, and particularly, the coupled-channel effect in the flavor space. According to our results, the state D-(*D-)(()*())[I(J(P)) = 0(1(+))] with double charm, the states (B) over bar (()*())(B) over bar (()*())[I(J(P)) = 0(1(+)), 1((+))], ((B) over bar (()*())(B) over bar (()*()))(s)[J(P) = 1(+), 2(+)] and ((B) over bar (()*())(B) over bar (()*()))(ss)[J(P) = 1(+), 2(+)] with double bottom, and the states D-(*())(B) over bar (()*())[I(J(P)) = 0(1(+)), 0(2(+))] with both charm and bottom might be good molecule candidates. However, the states D-(*D-)(()*())[I(J(P)) = 0(2(+)), 1(0(+)), 1(1(+)), 1(2(+))], (D-(*D-)(()*()))(s)[J(P) = 0(+), 2(+)] and (D-(*D-)(()*()))(ss)[J(P) = 0(+), 1(+), 2(+)] with double charm and the state D-(*())(B) over bar (()*())[I(J(P)) = 1(1(+))] with both charm and bottom are not supported to be molecules. |
