Inclusive quasielastic neutrino-nucleus scattering with energy density functional nuclear models

Abstract

In the quasielastic region, we calculate the inclusive charged-current neutrino-nucleus scattering from $^{40}$Ar. To explore the effect of uncertainties stemming from the nuclear structure, we use the KIDS (Korea-IBS-Daegu-SKKU) nuclear energy density functional and Skyrme force models, SLy4, SkI3, and MSk7. The models are selected to have distinct behavior of the density dependence of the symmetry energy and the effective mass of the nucleon. In the charged-current neutrino scattering, the single- and double-differential cross sections are calculated in various kinematics and total cross sections are shown in terms of the incident neutrino energy. The theoretical cross sections are compared with experimental data, and the roles of the effective mass and the symmetry energy are investigated in the charged-current neutrino-nucleus scattering.
