Is the Z+(4430) a radially excited state of Ds?
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/ π+ has not yet been seen while Z-> ' π can be seen.
