Using MiniBooNE NCEL and CCQE cross section results to constrain 3+1 sterile neutrino models
Abstract
The MiniBooNE NCEL and CCQE cross-section measurements (neutrino running) are used to set limits in the Δm2 — sin2 ϑμs plane for a 3+1 sterile neutrino model with a mass splitting 0.1 ≤ Δm2 ≤ 10.0 eV2. GENIE is used, with a relativistic Fermi gas model, to relate Ev and the reconstructed quantities measured. The issue of uncertainty in the underlying cross section model and its effect on the sterile neutrino limits is explored, and robust sterile neutrino limits are produced by fitting the sterile parameters and the axial-mass cross-section parameter simultaneously.
