Abstract
The total charged-current (CC) (anti)neutrino-nucleon cross section is usually estimated by the sum of contributions from quasielastic scattering (QES), single-pion production through baryon resonances (RES), and deep-inelastic scattering (DIS) with an appropriate scratching of the phase space of the RES and DIS contributions. However, the resulting total cross section is very sensitive to the value of the cutoff in invariant mass of the final hadron system produced in RES and DIS. We examine available experimental data on the QES and total CC cross sections in order to extract the best-fit value for this cutoff. By using the same data set, we attempt to adjust the poorly known values of the axial mass for QES and RES.
