X(3872) and Other Possible Heavy Molecular States
Xiang Liu ; Zhi-Gang Luo ; Yan-Rui Liu ; Shi-Lin Zhu ;
Date 1 Aug 2008
AbstractWe perform a systematic study of the possible molecular states composed of a pair of heavy mesons such as $Dar D$, $D^astar D$, $D^ast ar D^ast$ in the framework of the meson exchange model. The exchanged mesons include the pseudoscalar, scalar and vector mesons. Through our investigation, we find that (1) the structure X(3764) is not a molecular state; (2) There exists strong attraction in the range $r < 1$ fm for the $D^*ar D^*$ system with $J=0, 1$. If future experiments confirm $Z^+(4051)$ as a loosely bound molecular state, its quantum number is probably $J^{P}=0^+$. Its partner state $Phi^{**0}$ may be searched for in the $pi^0chi_{c1}$ channel; (3) The vector meson exchange provides strong attraction in the $D^ast ar D$ channel together with the pion exchange. A bound state solution exists with a reasonable cutoff parameter $Lambdasim 1.4$ GeV. X(3872) may be accommodated as a molecular state dynamically although drawing a very definite conclusion needs further investigation; (4) The $B^ast ar B$ molecular state exists.
