“…The most straightforward approach to this problem is the plane wave impulse approximation. It neglects all interactions between the outgoing nucleons and the nucleus [24], but it has been claimed that the distortions in the observables due to rescattering largely cancel for the ratio of proton to neutron yields [25]. This situation can be improved by means of a distorted wave impulse approximations, where the final nucleon scattering state is computed using optical potentials [26,27].…”

We have developed a model to describe the interactions of neutrinos with nucleons and nuclei, focusing on the region of the quasielastic and ∆(1232) peaks. We describe neutrino-nucleon collisions with a fully relativistic formalism which incorporates state-of-the-art parametrizations of the form factors for both the nucleon and the N − ∆ transition. The model has then been extended to finite nuclei, taking into account nuclear effects such as Fermi motion, Pauli blocking (both within the local density approximation), nuclear binding and final-state interactions. The in-medium modification of the ∆ resonance due to Pauli blocking and collisional broadening have also been included. Finalstate interactions are implemented by means of the Boltzmann-Uehling-Uhlenbeck (BUU) coupledchannel transport model. Results for charged current inclusive cross sections and exclusive channels as pion production and nucleon knockout are presented and discussed.

“…Furthermore, the input from scaling analysis of electron scattering data has been used to obtain NC cross sections [24]. Final-state interactions of the knocked out nucleons is neglected in several studies [13,14,19] while many treat them with the distorted wave impulse approximation [15,16,17,18,20] and with a multiple scattering Glauber model at higher energies [18]. The problem is that in those approaches it is not possible to take into account nucleon rescattering leading to energy losses, charge exchange and multiple nucleon emissions.…”

“…This fact has stimulated a considerable amount of theoretical work aiming at the description of nuclear effects in NC nucleon knockout reactions. The relativistic Fermi gas description of the nucleus has been adopted in many calculations [13,14,15,16]; others use wave functions for the bound nucleons, obtained in relativistic mean-field models [17,18,19,20]. The shell model [15,16] and the continuum random-phase approximation [21,22] have also been applied.…”

We have extended our model for charged current neutrino-nucleus interactions developed in Phys. Rev. C 73, 065502 (2006) to neutral current reactions. For the elementary neutrino-nucleon interaction, we take into account quasielastic scattering, ∆ excitation and the excitation of the resonances in the second resonance region. Our model for the neutrino-nucleus collisions includes in-medium effects such as Fermi motion, Pauli blocking, nuclear binding, and final-state interactions. They are implemented by means of the Giessen Boltzmann-Uehling-Uhlenbeck (GiBUU) coupledchannel transport model. This allows us to study exclusive channels, namely pion production and nucleon knockout. We find that final-state interactions modify considerably the distributions through rescattering, charge-exchange, and absorption. Side-feeding induced by charge-exchange scattering is important in both cases. In the case of pions, there is a strong absorption associated with the in-medium pionless decay modes of the ∆, while nucleon knockout exhibits a considerable enhancement of low energy nucleons due to rescattering. At neutrino energies above 1 GeV, we also obtain that the contribution to nucleon knockout from ∆ excitation is comparable to that from quasielastic scattering.

“…Note however, that our formalism can easily be generalized to other nuclei such as 4 He, 16 O, 40 Ca, and 208 Pb and production channels such as K + Σ + , K + Σ 0 , and K 0 Σ + . The most general form of the differential cross section is presented in Eq.…”

We present the investigation of the neutrino-induced strangeness associated production on nuclei in the relativistic plane wave impulse approximation (RPWIA) framework at the intermediate neutrino energies. In this study, the elementary hadronic weak amplitudes are embedded inside the nuclear medium for the description of the exclusive channels of neutrino-nucleus interactions. These amplitudes are extracted using a modeldependent evaluation of the hadronic vertex using the Born term approximation in which the application of the Cabibbo V-A theory and SU(3) symmetry are assumed to be valid. The nuclear effects are included via the bound state wavefunctions of the nucleon obtained from the relativistic mean field (RMF) models. Two kinematics settings are used to examine various distributions of the differential cross section in the rest frame of the target nuclei. The numerical results are obtained for the neutrino-induced chargedcurrent (CC) K + Λ-production on bound neutrons in 1s 1/2 and 1p 3/2 orbitals of 12 C.The angular distributions are forward peaked under both kinematic settings, whereas under the quasifree setting the cross sections tend mimic the missing momentum distribution of the bound nucleon inside the nucleus.
