Neutral Current Elastic Interactions in MiniBooNE

Neutral Current Elastic (NCE) interactions in MiniBooNE are discussed. In the neutrino mode MiniBooNE reported: the flux averaged NCE differential cross section as a function of four-momentum transferred squared, an axial mass M_{A} measurement, and a measurement of the strange quark spin content of the nucleon, Δs. In the antineutrino mode we present the background-subtracted data which is compared with the Monte Carlo predictions.
