| A search for the decay of B+ meson to rho +f0(980) is presented, using a sample of approximately 465 +/- 5 million BB¯ events (423.5 fb-1 of data) collected with the BABAR detector at the PEP-II asymmetric e+ e- collider at SLAC National Accelerator Laboratory. The following upper limit for the branching fraction at 90% confidence level is obtained: B (B+ → rho+ f0) x B (f0 → pipi) < 1.2 x 10 -6, representing an improvement compared to the previous result. |
