Measurement of the Differential q2 Spectrum and Forward-Backward Asymmetry for B K(*) + -
Abstract
We report measurements of the differential q2 spectrum and the forward-backward asymmetry for B K(*) +-, where represents an electron or a muon, with a data sample of 253 fb-1 accumulated on the (4S) resonance with the Belle detector at KEKB. We also present measurements of the branching fractions and their ratios.
