Search for tetraquark candidate Z(4430) in meson photoproduction
We propose a search for the newly discovered tetraquark candidate Z(4430) in photoproduction. Based on the Belle results we show that if Z(4430) is a genuine resonance, its significantly large coupling to $\psi^\prime\pi$ will cause it to stand out above the background in $\gamma p\to Z^+(4430) n\to \psi^\prime \pi^+ n$. We consider the dependence of the cross section for the quantum numbers ($J^{P}=1^{-}$, $1^{+}$ or $0^{-}$).
