Abstract

We present evidence for the exotic charged charmoniumlike state Z� c ð3900Þ decaying to J=ψπ� in semiinclusive weak decays of b-flavored hadrons. The signal is correlated with a parent J=ψπþπ− system in the invariant-mass range 4.2–4.7 GeV that would include the exotic structure Yð4260Þ. The study is based on 10.4 fb−1 of pp¯ collision data collected by the D0 experiment at the Fermilab Tevatron collider
