AbstractWe perform a full amplitude analysis of anti-B0 -> psi’ K- pi+ decays, with psi’ -> mu+ mu- or e+ e-, to constrain the spin and parity of the Z(4430)+. The J^P = 1+ hypothesis is favored over the 0- hypothesis at the 2.9 sigma level, while all other hypotheses with J <= 2 are excluded at the level of at least 4.3 sigma. The analysis is based on a 711 fb^-1 data sample that contains 772x10^6 B B pairs, collected at the Y(4S) resonance by the Belle detector at the asymmetric-energy e+ e- collider KEKB.
