### Description

MiniBooNE is an experiment operated at Fermilab looking for neutrino oscillations at $\Delta m^2 \sim 1eV^2$. MiniBooNE uses a neutrino beam produced from 8 GeV protons from the Fermilab Booster incident on a Be target. The Cerenkov detector located 541m from the target is a 12m diameter sphere filled with mineral oil and instrumented with 1280 inner and 240 veto PMTs. Neutral current elastic scattering (NCEL) is one of the most important interactions in MiniBooNE. To date we have recorded about 93K NCEL interactions candidates in neutrino mode with about 62% NCEL purity, which represents the world's biggest sample of such interactions. The MiniBooNE NCEL cross-section has been measured and will be presented as well as the measurement of the the axial vector mass ($M_A$).
