Relativistic descriptions of quasielastic charged-current neutrino-nucleus scattering: Application to scaling and superscaling ideas

摘要

The analysis of the recent experimental data on charged-current neutrino-nucleus scattering cross sections measured at MiniBooNE requires relativistic theoretical descriptions also accounting for the role of final-state interactions. In this work we evaluate inclusive quasielastic differential neutrino cross sections within the framework of the relativistic impulse approximation. Results based on the relativistic mean-field potential are compared with the ones corresponding to the relativistic Green's-function approach. An analysis of scaling and superscaling properties provided by both models is also presented.
