Abstract: Decays of B mesons that proceed through electroweak and radiative penguin amplitudes attract significant attention due to a number of observed discrepancies between the standard-model predictions and the results. Belle II is expected to perform measurements on channels closely related to those exhibiting anomalies and that are uniquely available to Belle II. These include b -> s(d) nu nubar and b -> s(d) tau+ tau- transitions. We present recent results on b -> s l+ l- , and b-> s nu nu transitions. In addition, decays of B mesons that proceed through radiative penguin amplitudes are probes of a large class of generic non-SM models for which Belle II has unique reach. We present recent results from an inclusive b -> s gamma analysis.
