Study of B0 → J/ψK(*)0π+π- decays with the collider detector at Fermilab

Journal article

The study of the decays B0 → J/ψK(*)0 π+π-, was reported. The study involved the creation of a uū or dd̄ quark pair in addition to a b̄ → c̄(cs̄) decay. Three-level dimuon trigger was used in the analysis. Events with two separate sets of atleast three linked hits in the muon chambers. The second level required drift chamber tracks with pT > 2.0 GeV/c. J/ψ → μ+μ- candidates, were accepted in the third level, with a reconstructed invariant mass between 2.8 and 3.8 GeV/c2.
