Electron Identification in Belle

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 $(92.4\pm 0.4)$ with a ${\pi }^{\pm }$ fake rate of $(0.25\pm 0.02)$ for the momentum range between 1.0 GeV/$c$ and 3.0 GeV/$c$ in laboratory frame.
