Previous fits of this form included data from a variety of PVES experiments (PVA4, HAPPEx, G0, SAMPLE) and the NCE neutrino and anti-neutrino data from BNL E734. These fits did not constrain the strangeness contribution to the axial form factor <math><mrow><msubsup><mrow><mi>G</mi></mrow><mrow><mi>A</mi></mrow><mrow><mi>s</mi></mrow></msubsup><mo>(</mo><msup><mrow><mi>Q</mi></mrow><mrow><mn>2</mn></mrow></msup><mo>)</mo></mrow></math> at low <math><msup><mi>Q</mi><mn>2</mn></msup></math> very well because there was no NCE data for <math><msup><mi>Q</mi><mn>2</mn></msup><mo>&lt;</mo><mn>0.45</mn><mtext> </mtext><mtext> </mtext><msup><mrow><mi>GeV</mi></mrow><mrow><mn>2</mn></mrow></msup></math>. Our new fit includes for the first time MiniBooNE NCE data from both neutrino and antineutrino scattering; this experiment used a hydrocarbon target and so a model of the neutrino interaction with the carbon nucleus was required. Three different nuclear models have been employed: a relativistic Fermi gas model, the superscaling approximation model, and a spectral function model. We find a tremendous improvement in the constraint of <math><msubsup><mi>G</mi><mi>A</mi><mi>s</mi></msubsup><mo>(</mo><msup><mi>Q</mi><mn>2</mn></msup><mo>)</mo></math> at low <math><msup><mi>Q</mi><mn>2</mn></msup></math> compared to previous work, although more data is needed from NCE measurements that focus on exclusive single-proton final states, for example from MicroBooNE."
