Description
Inclusive electron scattering cross sections from a hydrogen target at a beam energy of 10.6~GeV have been measured with data
collected from the CLAS12 spectrometer at Jefferson Laboratory. These data cover a wide kinematic area in invariant mass $W$ of the
final state hadrons from the meson threshold up to 2.5~GeV and in virtual photon four-momentum squared $Q^2$ from 1 to 10~GeV$^2$.
Owing to the nearly $4\pi$ acceptance of the CLAS12 detector, the data cover a broad $W$-range in each $Q^2$ bin. For the first time,
the inclusive electron scattering cross sections in the resonance region have become available for $Q^2$ up to 10~GeV$^2$ with a broad
$W$-coverage in each bin of $Q^2$. Comparison with the resonant contributions computed from the CLAS results on the $Q^2$-evolution of
the nucleon resonance electroexcitation amplitudes has demonstrated a promising opportunity to extend the information on their
$Q^2$-evolution up to 10~GeV$^2$. Together these results from CLAS and CLAS12 offer the prospect for insight into the nucleon parton
distributions at large fractional parton momenta $x$ for $W < 2.5$~GeV, covering the range of distances where the transition from
the strongly coupled to pQCD regimes is expected. In this talk, I will discuss the current status of the analysis and the future plan.
