| dc.description | The CLEO collaboration has studied two-body charmless hadronic decays of $B$ mesons into final states containing two pseudo-scalar mesons, or a pseudo-scalar and a vector meson. We summarize and discuss results presented during the winter/spring 1999 conference season, and provide a brief outlook towards future attractions to come. In particular, CLEO presented preliminary results on the decays $B^\pm \to π^\pmρ^0$ ($Br(B^\pm \to π^\pmρ^0) = (1.5 \pm 0.5 \pm 0.4)\times 10^{-5}$), $B\to π^\pmρ^\mp$ ($Br(B\to π^\pmρ^\mp)=(3.5^{+1.1}_{-1.0}\pm 0.5)\times 10^{-5}$), $B\to π^\pm K^{\star\mp}$ ($Br(B\to π^\pm K^{\star\mp}) = (2.2^{+0.8+0.4}_{-0.6-0.5})\times 10^{-5}$), and $B^\pm \to K^\pm π^0$ ($Br(B^\pm \to K^\pm π^0) = (1.5 \pm 0.4 \pm 0.3) \times 10^{-5}$) at DPF99, APS99, APS99, and ICHEP98 respectively. None of these decays had been observed previously. The first two of these constitute the first observation of hadronic $b\to u$ transitions. In addition, CLEO presented preliminary updates on a large number of previously published branching fractions and upper limits. | |
