Abstract

The MicroBooNE experiment is an 85 ton active mass liquid-argon time projection chamber located in the Fermilab Booster Neutrino Beamline. MicroBooNE’s ability to detect low-energy protons allows us to study single proton events with momenta as low as 300 MeV/c. We present a measurement of the fluxaveraged neutral-current elastic differential cross section for neutrinos scattering on argon as functions of four-momentum transfer squared, Q2 , proton kinetic energy, momentum and angle with respect to the beam direction. Our measured cross section as a function of Q2 goes as low Q2 = 0.10 GeV2 . This is our first step towards extracting the strange quark contribution to the axial form factor, which is not only the least-constrained contribution to the neutral-current elastic scattering cross section but is also crucial for understanding the strange quark contribution to the proton spin.
