Title: Nucleon resonance contributions to unpolarized inclusive electron scattering

Abstract

The first CLAS12 experiments will provide high-precision data on inclusive electron scattering observables at a photon virtuality Q 2 ranging from 0.05 to 12GeV 2 and center-of-mass energies W up to 4 GeV. In view of this endeavor, we present the modeling of the resonant contributions to the inclusive electron scattering observables. As input, we use the existing CLAS electrocoupling results obtained from exclusive meson electroproduction data off protons, and evaluate for the first time the resonant contributions based on the experimental results on the nucleon resonance electroexcitation. The uncertainties are given by the data and duly propagated through a Monte Carlo approach. In this way, we obtain estimates for the resonant contributions, important for insight into the nucleon parton distributions in the resonance region and for the studies of quark-hadron duality.
