In the present work, we propose to search the charmonium-like states ) and in the decay. In an effective Lagrangian approach, the branching ratios of 
and 
are estimated to be of order of 
and 
, respectively. The large production rate of 
could provide an important source of the production of from the semi-exclusive decay of b-flavored hadrons reported by D0 Collaboration, which can be tested by the exclusive measurements in LHCb.
