Properties of produced in collisions
We study the production of the exotic charged charmoniumlike state Z$$±\atop{c}$$(3900) in $$p$$$\bar{p}$$ collisions through the sequential process ψ(4260)→Z$$±\atop{c}$$(3900)π∓, Z$$±\atop{c}$$(3900)→J/ψπ±. Using the subsample of candidates originating from semi-inclusive weak decays of b-flavored hadrons, we measure the invariant mass and natural width to be M=3902.6$$+5.2\atop{-5.0}$$(stat)$$+3.3\atop{-1.4}$$(syst) MeV and Γ=32$$+28\atop{-21}$$(stat)$$+26\atop{-7}$$(syst) MeV, respectively. We search for prompt production of the Z$$±\atop{c}$$(3900) through the same sequential process. No significant signal is observed, and we set an upper limit of 0.70 at the 95% credibility level on the ratio of prompt production to the production via b-hadron decays. The study is based on 10.4 fb-1 of $$p$$$\bar{p}$$ collision data collected by the D0 experiment at the Fermilab Tevatron collider.
