Search for tetraquark candidate Z(4430) in meson photoproduction

Abstract

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 $0^{-}$).
