Measurements of Branching Fractions, Polarizations, and Direct CP -Violation Asymmetries in B→ρK* and B→f0(980)K* Decays

B. Aubert, R. Barate, M. Bóna, D Boutigny et autres

We report searches for $B$-meson decays to the charmless final states $\ensuremath{\rho}{K}^{*}$ and ${f}_{0}(980){K}^{*}$ with a sample of $232\ifmmode\times\else\texttimes\fi{}{10}^{6}$ $B\overline{B}$ pairs collected with the BABAR detector at the PEP-II ${e}^{+}{e}^{\ensuremath{-}}$ collider. We measure in units of ${10}^{\ensuremath{-}6}$ the following branching fractions, where …

Search for B0 Decays to Invisible Final States and to νν¯γ

B. Aubert, R. Barate, D. Boutigny, F. Couderc et autres

We establish upper limits on branching fractions for ${B}^{0}$ decays to final states where the decay products are purely invisible (i.e., no observable final state particles) and for ${B}^{0}$ decays to $\ensuremath{\nu}\overline{\ensuremath{\nu}}\ensuremath{\gamma}$. Within the standard model, these decays have branching fractions that …
