Data Release for Electron and Gamm-Ray Efficiencies (2011). There
is no related publication. The efficiencies were calculated in the
following way.
Two Monte Carlo data sets were generated. First was 50,000 single
electron events, second was 50,000 single gamma-ray events. These were
generated using the MiniBoonE event generator eGen, then processed with
standard MiniBooNE Monte Carlo code. The electron or
gamma-ray events were generated with the following specific
kinematics:
1. Flat energy distribution from 0 to 2000 MeV.
2. Isotropically distributed out to 610 cm radius (full tank radius).
3. Isotropically distributed angle.
The output Monte Carlo events were reconstruct with the standard
MiniBooNE analysis code, and then events were selected using the
standard oscillation particle identification cuts (including
Evis > 140 MeV, Radius < 500 cm, and dirt cuts). These are the same
cuts as in the oscillation PRL's
The following tables show the electron and gamma-ray efficiency as a
function of generated energy. It is noted that the monte carlo
generated energy is highly correlated (99.7%) with the reconstructed
visible energy, i.e. they are interchangeable. The systematic errors
on both the electron and gamma-ray efficiencies is 10% over the
entire energy range, and are uncorrelated.
Notes:
1. The efficiencies were found to be flat as a function of reconstructed angle.
2. The electrons generated for this study are single electrons, and are
different from CCQE events, which can have protons (or neutrons for
antineutrinos) in the final state. However a study showed electrons
from CCQE interactions and single electron events have similar efficiencies.
