Abstract
The Booster Neutrino Experiment (MiniBooNE) searches for v/, -* ve oscillations using the
0(1 GeV) neutrino beam produced by the Booster synchrotron at the Fermi National Accelerator
Laboratory (FNAL). The Booster delivers protons with 8 GeV kinetic energy (8.89 GeV/c momen-
tum) to a beryllium target, producing neutrinos from the decay of secondary particles in the beam
line. We describe the Monte Carlo simulation methods used to estimate the flux of neutrinos from
the beamline incident on the MiniBooNE detector for both polarities of the focussing horn. The
simulation uses the Geant4 framework for propagating particles, accounting for electromagnetic
processes and hadronic interactions in the beamline materials, as well as the decay of particles.
The absolute double differential cross sections of pion and kaon production in the simulation have
been tuned to match external measurements, as have the hadronic cross sections for nucleons and
pions. The statistical precision of the flux predictions is enhanced through reweighting and re-
sampling techniques. Systematic errors in the flux estimation have been determined by varying
parameters within their uncertainties, accounting for correlations where appropriate.
