Analysis of the Q^2-dependence of charged-current quasielastic processes in neutrino-nucleus interactions

Ankowski, Artur M., Benhar, Omar, Farina, Nicola

Understand

We discuss the observed disagreement between the Q^2 distributions of neutrino-nucleus quasielastic events, measured by a number of recent experiments, and the predictions of Monte Carlo simulations based on the relativistic Fermi gas model.

  • The results of our analysis suggest that these discrepancies are likely to be ascribable to both the breakdown of the impulse approximation and the limitations of the Fermi gas description.
  • Several issues related to the extraction of the Q^2 distributions from the experimental data are also discussed, and new kinematical variables, which would allow for an improved analysis, are proposed.
