Is the Z+(4430)Z+(4430) a radially excited state of DsDs?

We present the interpretation that the recently discovered Z+(4430)Z+(4430) by the Belle Collaboration can be a radial excitation of the cs¯ state, being consistent with an observed value of the product of branching ratios, B(B0→K∓Z±(4430))×B(Z±(4430)→π±ψ′)∼10−5B(B0→K∓Z±(4430))×B(Z±(4430)→π±ψ′)∼10−5. We give an explicit cs¯ candidate for this state by calculating the mass value in our semirelativistic quark potential model and also give a natural understanding for the facts that the decay mode Z→J/ψπ+Z→J/ψπ+ has not yet been seen while Z→ψ′πZ→ψ′π can be seen.
