Z+(4430) and Analogous Heavy Flavor States

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(o)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.
