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.
