Evidence for the decay X(3872)-->J/ psi omega

We present a study of the decays B0,+-->J/psi pi+pi-pi0K0,+, using 467×10[superscript 6]BB[over-bar] pairs recorded with the BABAR detector. We present evidence for the decay mode X(3872)-->J/psi omega, with product branching fractions B(B+-->X(3872)K+)×B(X(3872)-->J/psi omega)=[0.6±0.2(...

Description
Summary:We present a study of the decays B0,+-->J/psi pi+pi-pi0K0,+, using 467×10[superscript 6]BB[over-bar] pairs recorded with the BABAR detector. We present evidence for the decay mode X(3872)-->J/psi omega, with product branching fractions B(B+-->X(3872)K+)×B(X(3872)-->J/psi omega)=[0.6±0.2(stat)±0.1(syst)]×10[superscript -5], and B(B0-->X(3872)K0)×B(X(3872)-->J/psi omega)=[0.6±0.3(stat)±0.1(syst)]×10[superscript -5]. A detailed study of the pi+pi-pi0 mass distribution from X(3872) decay favors a negative-parity assignment.
