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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.
