Evidence for B-s(0)-\u3ephi phi decay and measurements of branching ratio and A(CP) for B+-\u3ephi K+

We present the first evidence of charmless decays of the B-s(0) meson, the decay B-s(0)-\u3ephi phi, and a measurement of the branching ratio BR(B-s(0)-\u3ephi phi) using 180 pb(-1) of data collected by the CDF II experiment at the Fermilab Tevatron collider. In addition, the BR and direct CP asymmetry for the B+-\u3ephi K+ decay are measured. We obtain BR(B-s(0)-\u3ephi phi)=[14(-5)(+6)(stat)+/- 6(syst)]x10(-6), BR(B+-\u3ephi K+)=[7.6 +/- 1.3(stat)+/- 0.6(syst)]x10(-6), and A(CP)(B+-\u3ephi K+)=-0.07 +/- 0.17(stat)(-0.02)(+0.03)(syst). Both decays are governed in the standard model by second order (penguin) b -\u3e s(s) over bar s amplitudes

Evidence for B-s(0)->phi phi decay and measurements of branching ratio and A(CP) for B+->phi K+

We present the first evidence of charmless decays of the $B_s^0$ meson, the decay \phiphi, and a measurement of the Branching Ratio \BR(\phiphi) using $180 {\rm pb}^{-1}$ of data collected by the \cdfii experiment at the Fermilab Tevatron collider. In addition, the BR and direct CP asymmetry for the \phik\ decay are measured. We obtain: \BR (\phiphi) = (14 \ase{6}{5}(stat.) \pm 6(syst.)) \times 10^{-6}, \BR (\phik) = (7.6 \pm 1.3(stat.) \pm 0.6(syst.)) \times 10^{-6}, and \ACP(\phik) = -0.07 \pm 0.17 (stat.) \ase{0.03}{0.02} (syst.). Both decays are governed in the Standard Model by second order (penguin) b \myto s\bar{s}s amplitudes.Comment: Submitted to Physical Review Letters Fixed few typos plus additional comments to introduction suggested by referee'
