Abstract

We present the results of an amplitude analysis of B¯0→J/ψK-π+ decays. A new charged charmoniumlike state Zc(4200)+ decaying to J/ψπ+ is observed with a significance of 6.2σ. The mass and width of the Zc(4200)+ are 4196-29-13+31+17MeV/c2 and 370-70-132+70+70MeV, respectively; the preferred assignment of the quantum numbers is JP=1+. In addition, we find evidence for Zc(4430)+→J/ψπ+. The analysis is based on a 711fb-1 data sample collected by the Belle detector at the asymmetric-energy e+e- collider KEKB.
