Abstract
To achieve its design goals, the next generation of neutrino-oscillation
accelerator experiments requires percent-level predictions of neutrino-nucleus
cross sections supplemented by robust estimates of the theoretical
uncertainties involved. The latter arise from both approximations in solving
the nuclear many-body problem and in the determination of the single- and
few-nucleon quantities taken as input by many-body methods. To quantify both
types of uncertainty, we compute flux-averaged double-differential cross
sections using the Green's function Monte Carlo and spectral function methods
as well as different parameterizations of the nucleon axial form factors based
on either deuterium bubble-chamber data or lattice quantum chromodynamics
calculations. The cross-section results are compared with available
experimental data from the MiniBooNE and T2K collaborations. We also discuss
the uncertainties associated with $N\rightarrow \Delta$ transition form factors
that enter the two-body current operator. We quantify the relations between
neutrino-nucleus cross section and nucleon form factor uncertainties. These
relations enable us to determine the form factor precision targets required to
achieve a given cross-section precision.
