“…Explicit expressions for the RPA corrections to the hadronic tensor are given in Appendix A of Ref [19]. This RPA approach, buih up with the single-particle states of the Local Fermi Gas is simpler than other more sophisticated methods such as continuum RPA and applies only to inclusive processes, but it incorporates explicitly n, p exchange and A-hole states and can be naturally inserted in a unified framework to study different neutrino-induced reactions like inclusive quasielastic scattering, nucleon knockout and pion production [21]. Moreover, it had been Only the terms that contribute to CCQE are shown.…”

Abstract. We present our description of neutrino induced charged current quasielastic scattering (CCQE) in nuclei at energies relevant for the MiniBooNE experiment. In our framework, the nucIcons, with initial momentum distributions according to the Local Fermi Gas model, move in a density-and momentum-dependent mean field potential. The broadening of the outgoing nucleons due to nucleon-nucleon interactions is taken into account by spectral fimctions. Long range (RPA) correlations renormalizing the electroweak strength in the medium are also incorporated. The background from resonance excitation events that do not lead to pions in the final state is also predicted by propagating the outgoing hadrons with the Giessen semiclassical BUU model in coupled channels (GiBUU). We achieve a good description of the shape of the CCQE Q^ distribution extracted from data by MiniBooNE, thanks to the inclusion of RPA correlations, but imderestimate the integrated cross section when the standard value of M^ = 1 GeV is used. Possible reasons for this mismatch are discussed.

We investigate neutrino-nucleus interactions at energies around 1 GeV. In this regime, the main contributions to the cross sections come from quasi-elastic and ∆ production processes. Our formalism, based on the Impulse Approximation is well suited to describe both types of interactions. We focus on a series of important nuclear effects in the interaction of electron neutrinos with 16 O, also relevant to future β-Beams. Our results show that the Fermi gas model, widely used in data analysis of neutrino experiments, overestimates the total cross sections by as much as 20 %.

“…For the incoming nucleon, only the real part of the self energy is taken into account [22]. The final-state nucleon is propagated through the nucleus with the coupled-channel hadronic transport model which accounts for elastic and inelastic collisions with the other nucleons [23]. Martini The Martini model [24] is an extension of the model proposed by Marteau [25].…”
