Abstract
We investigate the possible rescattering effects which may contribute to the process . It is shown that the rescattering via the open-charmed meson loops, and rescattering via the loops may simulate the structures of and , respectively. However, if the quantum numbers of () are (), it is hard to to ascribe the observation of and to the -wave threshold rescattering effects, which implies that and could be genuine resonances. We also suggest that may be the conventional orbitally excited state .
