N2 - The strange quark contribution to the spin of the proton can be determined from neutral-current elastic neutrino-proton scattering. At zero four-momentum transfer the axial form factor in this process becomes a linear combination of the net spin contributions from the individual quark flavors to the spin of the proton. MicroBooNE’s ability to detect low-energy protons allows it to detect these events with negative four-momentum transfer squared as low as Q 2 ' 0.1 GeV2 /c2 . We present a selection of neutral-current elastic events in a subset of MicroBooNE neutrino data and outline a plan to extract the strange part of the axial form factor from this selection in the full data set.
