The two-body open charm decays Z(+)(4430)-> D+(D) over bar*(0), D*(+)(D) over bar (0), D*(+)(D) over bar*(0) occur through the rescattering mechanism and their branching ratios are strongly suppressed if Z(+)(4430) is a D-1(D) over bar* molecular state.

The two-body open charm decays Z(+)(4430)-> D+(D) over bar*(0), D*(+)(D) over bar (0), D*(+)(D) over bar*(0) occur through the rescattering mechanism and their branching ratios are strongly suppressed if Z(+)(4430) is a D-1(D) over bar* molecular state. In contrast, Z(+)(4430) falls apart into these modes easily with large phase space and they become the main decay modes if Z(+)(4430) is a tetraquark state. Experimental search of these two-body open charm modes and the hidden charm mode chi(cJ)rho will help distinguish different theoretical schemes.
