We perform a full amplitude analysis of B0→ψ′K+π− decays, with ψ′→μ+μ− or e+e−, to constrain the spin and parity of the Z(4430)−. The JP=1+ hypothesis is favored over the 0−, 1−, 2− and 2+ hypotheses at the levels of 3.4σ, 3.7σ, 4.7σ and 5.1σ, respectively. The analysis is based on a 711 fb−1 data sample that contains 772×106 BB¯ pairs collected at the Υ(4S) resonance by the Belle detector at the asymmetric-energy e+e− collider KEKB.7 MoreReceived 20 June 2013DOI:https://doi.org/10.1103/PhysRevD.88.074026© 2013 American Physical Society
