Neutrino Flux

The MiniBooNE neutrino flux calculations are described in detail in PRD 79, 072002 (2009) and arXiv:0806.1449

π+ production

    Data sets:
  • M.G. Catanesi et al. [HARP Collaboration], ``Measurement of the production cross-section of positive pions in the collision of 8.9-GeV/c protons on beryllium,'', arXiv:hep-ex/0702024
  • E910 @6.4,12.3 GeV/c
  • Parameterization: J.R. Sanford and C.L. Wang, BNL Internal Report # BNL11479

K+ production

    Data sets:
  • T. Abbott et al, Phys. Rev. D45, 3906 (1992), @14.6 GeV/c
  • J.V. Allaby et al, CERN 70-12 Nuclear Physics Division April 23, 1970, @19.2 GeV/c
  • D. Dekkers et al, Phys. Rev. 137, B962 (1965), @20.9 GeV/c
  • G.J. Marmer et al, Phys. Rev.; Vol.179,No. 5; (1969), @12.3 GeV/c
  • Aleshin et al., ITEP-77-80 (1977), @9.5 GeV/c
  • Voronsov et al., ITEP-88-11 (1988), @10.1 GeV/c
  • Eichten et al.,Nucl. Phys. B44 (1972) 333-343, @24.0 GeV/c
  • Parameterization: Feynman scaling based
  • Shape of K+ neutrino flux is fixed by parameterization, normalization information comes from high energy neutrino events from K+ and the Little Muon Counter.

K0 production

    Data sets:
  • E910 12.3, 17.6 GeV/c
  • F. Abe et a., "Production of Neutral Strange Particles K0(s) and Lambda0 by 12-Gev Protons on Nuclear Targets", Phys. Rev. D 36, 1302, @12 GeV/c
  • Parameterization: Sanford Wang parameterization
  • Normalization and shape are set from this parameterization

Secondary interactions

  • ~7% of our muon neutrinos from π+ come from re scattered protons. Mesons also interact with the horn, target, and concrete. We use custom models of p,n,π+, π- on Be, Al for our secondary production models. HARP ran with a shorter, 'thin' version of our target, but also took data with a longe, 'thick' target to check our reinteraction models.
