| Publication Abstract: | We use the nCTEQ analysis framework to investigate nuclear PDFs in the region of large x and intermediate to low Q^2, with special attention to recent JLab Deep Inelastic Scattering (DIS) data on nuclear targets. In particular, we focus on the kinematic region which is often excluded by W and Q^2 cuts in global PDF analyses. As we relax the W and Q^2 cuts, we enter a new kinematic region which introduces new phenomenology. In particular, we study the impact of (i) target mass corrections, (ii) higher twist corrections, (iii)~deuteron corrections, and (iv)~large-$x$ nuclear corrections. Using the above tools, we produce a nPDF set (nCTEQ15HIX) which yields a good description of the new JLab data in this challenging kinematic region. |
