Description
We present the results of a new search for B-meson decays to omega omega, and omega phi. These modes, yet unseen, are related to B -> phi K* decays via an SU(3) rotation. Their study can therefore provide information regarding the unexpectedly small value of the longitudinal spin component (f_L) measured in B -> phi K* decays.
We also report the first Dalitz-plot analysis of charged B mesons decays to Ks pi+ pi0. We observe an excess of signal events and measure the branching fractions and CP asymmetries, for the different resonant decay modes and inclusively.
The two analyses are performed using the full BABAR dataset of 471 million BBbar events collected at the Upsilon_(4S) resonance.
