Precision neutrino oscillation experiments of the future-of which DUNE is a prime example-require reliable event generator tools. The 1-4 GeV energy regime, in which DUNE will operate, is marked by the transition from the low-energy nuclear physics domain to that of perturbative QCD, resulting in rich and highly complex physics. Given this complexity, it is important to establish a validation procedure capable of disentangling the physical processes and testing each of them individually. Here, we demonstrate the utility of this approach by benchmarking the GENIE generator, currently used by all Fermilab-based experiments, against a broad set of inclusive electron-scattering data. This comparison takes advantage of the fact that, while electron-nucleus and neutrino-nucleus processes share a lot of common physics, electron scattering gives one access to precisely known beam energies and scattering kinematics. Exploring the kinematic parameter range relevant to DUNE in this manner, we observe patterns of large discrepancies between the generator and data. These discrepancies are most prominent in the pion-producing regimes and are present not only in medium-sized nuclei, including argon, but also in deuterium and hydrogen targets, indicating mismodeled hadronic physics. Several directions for possible improvement are discussed.

“…They have used the model to study the modification of F 2 structure functions in the nuclear medium and have suggested that the change the spin structure function of a bound nucleon in the nuclear matter is roughly twice as large as the change in the spin independent structure function. It may be mentioned that recently Osipenko et al [30] have reported the measurement of inclusive electron scattering from CLAS at JLab. They have evaluated the F 2 structure functions and the corresponding moments.…”

The properties of the nucleons in nuclear medium have been investigated in the context of the flux tube model incorporating strangeness (ss) contribution to proton structure in conformity with the experimental indication.Proton is described as a pentaquark system with strange quark contribution whereas neutron is described in three quark configuration. The Quasi particle model of diquark is used to describe the structures of the nucleons. Modifications of the properties like swelling, mass, incompressibility, ratio of the structure functions (), Gottfried Sum rule for nucleons in nuclear medium have been studied and significant effects have been observed. It has been suggested that the change of the size degree of freedom of the nucleon in the nuclear medium plays an important role in describing the properties in medium. The results are discussed in detail and compared with existing experimental and theoretical predictions. Some interesting observations are made.
