<div class="PlainText">Dear All,<br>
<br>
I would like to present at the upcoming April APS meeting. Here is my<br>
abstract for comments and suggestions.<br>
<br>
Electron scattering data off protons from the CLAS12 detector in Hall B at<br>
Jefferson Laboratory have become available and cover a wide kinematic<br>
range in W up to 2.5 GeV and Q2 up to 9 GeV2, offering new opportunities<br>
to explore inclusive, semi-inclusive, and fully exclusive reactions. A<br>
study that aims to extract the inclusive electroproduction cross sections<br>
from the CLAS12 data collected at a beam energy of 10.6 GeV from an<br>
unpolarized liquid-hydrogen target is now almost finished and preliminary<br>
results will be presented. Because of the large acceptance of CLAS12,<br>
these data offer a unique opportunity to measure inclusive cross sections<br>
at W from the meson electroproduction threshold to 2.5 GeV within any<br>
given Q2-bin from 2.5 to 9 GeV2. This unique W - coverage at fixed<br>
Q2-values is of particular importance for the extension of our knowledge<br>
on the nucleon parton distribution function from the data on F2 structure<br>
function in the resonance region. Broad coverage over Q^<9.0 GeV^2 offers<br>
promising opportunity to explore the mechanisms underlying the nucleon PDF<br>
evolution in the transition from strongly-coupled to perturbative QCD<br>
regimes.<br>
<br>
Best regards,<br>
Valerii<br>
