Comprehensive Study on Neutrino Flux Uncertainty in MiniBooNE Experiment

This study delves into flux uncertainty arising from finite HARP statistics in MiniBooNE Experiment, considering various parent mesons and neutrino energies. It explores uncertainties for different geometrical coverages and forward analysis scenarios. Statistical errors are carefully analyzed across neutrino energies and meson types.

  1. MiniBooNE Flux Uncertainty Arising from Finite HARP Statistics • Consider  and e flux combined as well as e’s from kaon decay alone. • Flux uncertainty as a function of parent meson and neutrino energy. • Flux uncertainty as a function of parent meson averaged over all neutrino energies. • Uncertainties studied for 4 geometrical coverage as well as for forward analysis only.

  2. Neutrino Flux Uncertainty Achievable from 1.4M HARP Events.(4 geometrical acceptance) Uncertainty integrated over neutrino energy.  and e combined flux uncertainty verses neutrino energy for 5 parent meson types ( +, -, K+, K-, K0 ) *statistical error only

  3. e Flux Uncertainty Achievable from 1.4M HARP Events.(4 geometrical acceptance) Uncertainty integrated over neutrino energy. e flux uncertainty from kaon decay verses neutrino energy. *statistical error only

  4. HARP Forward Analysis(excluding the TPC) Statistics reduced accordingly for partially detected cones. 100% uncertainty assumed for undetected cones.

  5. Neutrino Flux Uncertainty Achievable from 1.4M HARP Events.(forward analysis only) Uncertainty integrated over neutrino energy.  and e combined flux uncertainty verses neutrino energy for 5 parent meson types ( +, -, K+, K-, K0 ) * Additional uncertainty mainly at low energies. *statistical error only

  6. e Flux Uncertainty Achievable from 1.4M HARP Events.(forward analysis only) Uncertainty integrated over neutrino energy. * Additional uncertainty mainly at low energies. e flux uncertainty from kaon decay verses neutrino energy. *statistical error only
