Nuclear effects in (anti)neutrino charge-current quasielastic scattering at MINER nu A kinematics

We compare the characteristics of the charged-current quasielastic (anti)neutrino scattering obtained in two different nuclear models, the phenomenological SuperScaling Approximation and the model using a realistic spectral function S(p, epsilon) that gives a scaling function in accordance with the...
