Ab Initio Study of (ν_{ℓ},ℓ^{-}) and (ν[over ¯]_{ℓ},ℓ^{+}) Inclusive Scattering in ^{12}C: Confronting the MiniBooNE and T2K CCQE Data

We carry out an ab initio calculation of the neutrino flux-folded inclusive cross sections measured on ^{12}C by the MiniBooNE and T2K Collaborations in the charged-current quasielastic regime. The calculation is based on realistic two- and three-nucleon interactions, and on a realistic nuclear elec...
