Abstract

We report a study of the decays B0J/ψK(*)0π+π, which involve the creation of a uu¯ or dd¯ quark pair in addition to a b¯c¯(cs¯) decay. The data sample consists of 110pb1 of pp¯ collisions at s=1.8TeV collected by the CDF detector at the Fermilab Tevatron collider during 1992–1995. We measure the branching fractions to be B(B0J/ψK*0π+π)=(6.6±1.9±1.1)×104 and B(B0J/ψK0π+π)=(10.3±3.3±1.5)×104. Evidence is seen for contributions from ψ(2S)K(*)0, J/ψK0ρ0, J/ψK*+π, and J/ψK1(1270).
