Search For The D~*(?)~* Molecular State Z_c(4000) In The Reaction Of B~-→J/ψρ~0K~-

In recent decades,many kinds of charmonium-like prime states(named as X,Y,Z states)have been found in experiments,which provides a good platform for the study of multi quark dynamics.There are various explanations for the internal structure of these states.Hadron molecular states,similar to deuterons,play an important role because the prediction of these states can be carried out under controllable uncertainty.Based on the prediction of a molecular state Zc(4000)with isospin I=1 in the coupled channels approach,we suggest to search for this state in the reaction of B-→J/ψρ0K-.By taking into account the final state interactions of J/ψρ and D*D*,and the contribution of the K1(1270)resonance,we find that the J/ψρ mass distribution shows a peak around 4000 MeV,which could be associated to the D*D*molecular state Zc(4000).In this paper,we introduce the B-→J/ψρ0K-decay process in detail,consider the interaction between tree graph and final state,and analyze the uncertainty of weak decay vertex.We suggest that the experimentally looking for the D*D*molecular state Zc(4000)in the B-→J/ψρ0K-process.This work provides an important step to understand the properties of strange hadrons.and our predictions can be tested by the Belle Ⅱ and LHCb in future.
