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

Abstract

We present the interpretation that the recently discovered Z^+(4430) by the Belle Collaboration can be a radial excitation of the cs-bar state. We give an explicit cs-bar candidate for this state by calculating the mass value in our semirelativistic quark potential model and also give a natural interpretation on the reason why the decay mode Z-> J/ψπ^+ has not yet been seen while Z-> ψ' πcan be seen.
