Inclusive Electron Scattering in the Resonance Region at CLAS12

ORAL

Abstract

Inclusive electron scattering yields from a hydrogen target at a beam energy of 10.6 GeV have been measured with the CLAS12 spectrometer at Jefferson Laboratory. These data cover a wide kinematic area in invariant mass of the final hadrons W up to 3 GeV and four- momentum transfer Q$^{\mathrm{2}}$ from 1 to 10 GeV$^{\mathrm{2}}$. These will be used to measure inclusive cross sections in the range of W\textless 3.0 GeV in Q$^{\mathrm{2}}$ bins of \textless 0.3 GeV$^{\mathrm{2}}$. Knowledge on the W-evolution of the inclusive cross sections is of particular importance in order to gain insight into the parton distributions in the resonance region and their evolution over a wide range of Q$^{\mathrm{2}}$. The CLAS results on nucleon resonance electrocouplings for the first time allow us to evaluate the s-channel resonance contributions in inclusive electron scattering observables for Q$^{\mathrm{2}}$\textless 6.0 GeV$^{\mathrm{2}}$, offering new prospects for the exploration of the parton distributions in the resonance region and for studies of quark-hadron duality. The current status of this analysis will be shown and the longer-term plans will be discussed.
