Separating form factor and nuclear model effects in quasielastic neutrino-nucleus scattering

When studying neutrino oscillations an understanding of charged current quasielastic (CCQE) neutrino-nucleus scattering is imperative. This interaction depends on a nuclear model as well as knowledge of form factors. In the past, CCQE data from the MiniBooNE experiment was analyzed assuming the Relativistic Fermi Gas (RFG) nuclear model [1], an axial dipole form factor in [2], and using the the z-expansion for the axial form factor in [3]. We present the first analysis that combines a non-RFG nuclear model, in particular the Correlated Fermi Gas nuclear model (CFG) of [4], and the z expansion for the axial form factor. This will allow us to separate form factor and nuclear model effects in CCQE scattering. References: [1] R. A. Smith and E. J. Moniz, Nucl. Phys. B 43, 605 (1972). [2] A. A. Aguilar-Arevalo et al.
