We report on preliminary measurements of branching fractions, charge-parity-violating asymmetries, and longitudinal polarization fractions in charmless bottom-meson decays from the Belle~II experiment. We use samples of electron-positron collisions collected in 2019 and 2020 at the $Upsilon(4S)$ resonance, corresponding to integrated luminosities of up to 62.8 ${rm fb^{-1}}$. The results are compatible with known values, indicating good understanding of early detector performance.

We report on the reconstruction of various charmless $B$ decays from electron-positron collisions at the energy corresponding to the $Upsilon(4S)$ resonance collected with the Belle II detector at the SuperKEKB collider. We use simulation to devise o
ptimized event selections and apply them to the full data set collected in 2019, corresponding to 8.7,fb$^{-1}$ of integrated luminosity. We fit the difference between half of the collision energy and the $B$ candidate energy (in the $Upsilon(4S)$ frame) for events restricted to a signal-rich range in beam-energy-constrained mass to search for charmless signals. Signal yields of approximately 80, 15, 20, 30, 90, and 160 decays are reconstructed for the channels $B^0 to K^+pi^-$, $B^0 to pi^+pi^-$, $B^+ to K^0_S(to pi^+pi^-)pi^+$, $B^+ to K^+pi^0(to gammagamma)$, $B^+ to K^+K^-K^+$, and $B^+ to K^+pi^-pi^+$, respectively. Yields and background contaminations are compatible with those expected from simulation and comparable with those obtained by the Belle experiment. The results show a good understanding of the detector performance and offer a reliable basis to assess projections for future reach.
We report on first measurements of branching fractions~($mathcal{B}$) and CP-violating charge asymmetries~($mathcal{A}$) in charmless $B$ decays at Belle~II. We use a sample of electron-positron collisions collected in 2019 and 2020 at the $Upsilon(4
S)$ resonance and corresponding to $34.6$,fb$^{-1}$ of integrated luminosity. We use simulation to determine optimized event selections. The $Delta E$ distributions of the resulting samples, restricted in $M_{rm bc}$, are fit to determine signal yields. Signal yields are corrected for efficiencies determined from simulation and control data samples to obtain branching fractions and CP-violating asymmetries for flavour-specific channels. These are the first measurements in charmless decays reported by Belle~II. Results are compatible with known determinations and show detector performance comparable with the best Belle results offering a reliable basis to assess projections for future reach.
Rare and flavour-changing neutral current decays of the B meson are an important probe in the search for physics beyond the Standard Model. There have recently been several anomalies in rare B decays, and lepton-universality measurements, specificall
y involving the $bto sell^+ell^-$ quark transition. These results tend towards a non-Standard-Model interpretation. The Belle II experiment is a next-generation b physics experiment located at SuperKEKB, an upgraded B factory $e^+e^-$ collider, in Tsukuba, Japan. The first collisions are expected in early 2018 with full physics data expected in 2019. This document describes prospects for several rare B decays at Belle II including $bto sell^+ell^-$ processes and others, such as $bto(s,,d)gamma$ and $bto s ubar u$. Areas where the Belle II program is complementary to that of the currently running LHCb experiment are highlighted.
We present new results from the study of B decays at SLD: a measurement of the inclusive double-charm branching fraction in B-hadron decays and a search for the rare exclusive charmless decays B+ --> Rho0 Pi+(K+) and B+ --> K*0 Pi+(K+). Using a novel
technique which consists of counting charged kaons produced at the secondary (B) vertex and the tertiary (D) vertex, we measure BR(B-->DDbarX) = 0.188 +- 0.025(stat) +- 0.059(syst). Another technique, based on the comparison of the charge of the D vertex to the flavor of the B hadron at production, yields a consistent result. In the search for rare exclusive B+ decays, no candidates were found and competitive branching ratio upper limits are derived.
We report a study of the charmless hadronic decay of the charged $B$ meson to the three-body final state $K^+ K^- pi^+$. The results are based on a data sample that contains $772times10^6$ $B bar{B}$ pairs collected at the $Upsilon(4S)$ resonance wit
h the Belle detector at the KEKB asymmetric-energy $e^+ e^-$ collider. The measured inclusive branching fraction and the direct $CP$ asymmetry are $(5.38pm0.40pm0.35)times 10^{-6}$ and $-0.170pm0.073pm0.017$, respectively, where the first uncertainties are statistical and the second are systematic. The $K^{+}K^{-}$ invariant mass distribution of the signal candidates shows an excess in the region below $1.5$ GeV/$c^2$, which is consistent with the previous studies from BaBar and LHCb. In addition, strong evidence of a large direct $CP$ asymmetry is found in the $K^{+}K^{-}$ low-invariant-mass region.
