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 $\hat{I}”m^2-{\sin }^2{\vartheta }_{\hat{I}¼s}$ plane for a 3+1 sterile neutrino model with a mass splitting $0.1\le \hat{I}”m^2\le 10.0$ eV${}^2$. GENIE is used, with a relativistic Fermi gas model, to relate $E_{\hat{I}}½$ 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.
