We present evidence for the exotic charged charmonium-like state Zc±(3900) decaying to J/ψπ± in semi-inclusive weak decays of b-flavored hadrons. The signal is correlated with a parent J/ψπ+π− system in the invariant mass range 4.2−4.7 GeV that would include the exotic structure Y (4260). The study is based on 10.4 fb−1 of pp collision data collected by the D0 experiment at the Fermilab Tevatron collider.
