Search for Muon Neutrino Disappearance in a Short-Baseline Accelerator Neutrino Beam

TL;DR

This paper reports a search for muon neutrino disappearance in a short-baseline accelerator beam, combining data from SciBooNE and MiniBooNE to improve sensitivity in the 0.5-40 eV^2 Δm^2 region.

Contribution

It introduces a combined analysis method using SciBooNE and MiniBooNE data to enhance sensitivity to muon neutrino disappearance.

Findings

Improved sensitivity over previous single-detector analyses.

Constraint on neutrino flux from SciBooNE data.

Preliminary results indicating potential for new limits on neutrino oscillations.

Abstract

We report a search for muon neutrino disappearance in the $\Delta m^{2}$ region of 0.5-40 $eV^2$ using data from both SciBooNE and MiniBooNE experiments. SciBooNE data provides a constraint on the neutrino flux, so that the sensitivity to $\nu_{\mu}$ disappearance with both detectors is better than with just MiniBooNE alone. The preliminary sensitivity for a joint $\nu_\mu$ disappearance search is presented.
