Query: Backgrounds in Neutrino Appearance Signal at MiniBooNE   The MiniBooNE (Booster Neutrino Experiment) experiment is a precise search
for neutrino oscillations but is crucially sensitive to background processes
that would mimic an oscillation signal. The background sources include
intrinsic $\nu_{e}$ from kaon and muon decays, mis-identified $\pi^{0}$, gammas
from radiative delta decays, and muon neutrino events mis-identified as
electrons. A summary of these backgrounds and the tools to handle them is
presented.
