Abstract: (arXiv)
MiniBooNE charge current quasi-elastic double differential cross section data are analyzed and confronted with predictions of two theoretical nucleus models: Fermi gas and spectral function. The fitting procedure includes the overall flux uncertainty multiplicative factor. In order to obtain a reliable value of the axial mass, bins with large contribution from small momentum transfer are eliminated from the analysis. It is shown that the best fit axial mass value becomes smaller as the momentum transfer cut is more restrictive. For qcut=500q_{cut}=500~MeV/c the obtained values of axial mass are MA=1350±66M_A=1350\pm 66~MeV for the Fermi gas and MA=1343±60M_A=1343\pm 60~MeV for the spectral function. The value MA=1030M_A=1030~MeV is excluded on the level which goes far beyond 5σ5\sigma.
