主　　题：nonrelativistic quark model hadronic molecule coupled-channel analysis 

摘      要：We have studied Z+(4430)as a D*D1 molecule from the quark model,state mixing effect is considered by solving the coupled channel Schrdinger equation numerically. More precise measurements of Z+(4430)mass and width,partial wave analysis are helpful to understand its structure. If it lies below the D*D1 threshold,molecule interpretation with JP=1-is favored,and JP=0-can not be ruled out. Otherwise Z+(4430)may be a virtual state with JP=2-. The analogous heavy flavor mesons Z+bb and Z++bc are considered as well,and the masses predicted in our model are in agreement with the predictions from the potential model and QCD sum rule.
