Quasielastic charged-current neutrino scattering in the scaling model with relativistic effective mass

Understand

We use a recent scaling analysis of the quasielastic electron scattering data from $^{12}$C to predict the quasielastic charge-changing neutrino scattering cross sections within an uncertainty band.

• We use a scaling function extracted from a selection of the $(e,e')$ cross section data, and an effective nucleon mass inspired by the relativistic mean-field model of nuclear matter.
• The corresponding super-scaling analysis with relativistic effective mass (SuSAM*) describes a large amount of the electron data lying inside a phenomenological quasielastic band.
• The effective mass incorporates the enhancement of the transverse current produced by the relativistic mean field.
