| 英文摘要 | Stimulated by recent experimental observation of X-1(2900) just below the (D) over bar K-1 threshold, we extend our previous study of (D) over bar D-1 S-wave bound state by vector meson exchange to (D) over bar K-1 system as well as similar (D) over barK(1), D1K and DK1 systems to look for possible bound states. We find that the potential of DK1 is attractive and strong enough to form bound states with mass around 3110 MeV for DK1(1270) and 3240 MeV for DK1(1400). D1K is also attractive but weaker, hardly enough to form bound states. While DK1 becomes further less attractive, the potential between D1K is the weakest, definitely too weak to form any bound state, which excludes the recently observed X-1(2900) to be a (D) over bar K-1 bound state. We also give the decay properties of the predicted (DK1) bound states. |
