The study of ν-oscillations have renewed interest in ν-nucleus interactions. At energy of O(1 GeV), nuclear effects play an important role. The MicroBooNE experiment is an effort to exploit the advantages of Liquid Argon (LAr) detectors for measurements of ν-interactions, with a goal to address the excess of events at low energies observed by MiniBooNE. 

We propose to extract ν-neutron quasi-elastic cross-sections and improve the understanding of nuclear physics impact on ν-nucleus measurements, from the analysis of charge current ν-scattering events with one or two protons and no pions in the final state. This will be accomplished by formulating an algorithm for proton reconstruction and QE event identification in LAr detectors, followed by analysis of the cosmic and neutrino induced MicroBooNE data, with one and two protons tracks.
