| ABSTRACT: |
Recently, many exotic charmonium-like states have been observed, which
motivated heated discussions on their natures and explorations about
the existence of possible heavy quark molecules. The isoscalar
Dar{D} is the simplest hidden charm system. To understand better
whether a bound state is possible in this system, the S and P wave
Dar{D} scatterings are studied intensively in a meson exchange
model. We investigate their production by including the Dar{D}
rescattering effect. We also extend similar studies to the Bar{B}
case. From the line shape of the production cross sections, useful
information about S wave molecular bound states is obtained. |
