  • Abstract
    We report on electron identification methods and their performance in the Belle experiment at the KEK-B asymmetric B-Factory e+e− storage ring. Electrons are selected using a likelihood approach that takes information from the electromagnetic calorimeter, the central drift chamber, and the silica aerogel Cherenkov counters as input. We achieve an electron identification efficiency of (92.4±0.4)% with a π± fake rate of (0.25±0.02)% for the momentum range between 1.0 and 3.0 GeV/c in laboratory frame.
