Description
We discuss nuclear corrections to the DIS structure functions focusing at the region of large Bjorken $x$. We present a detailed comparison with recent measurements of nuclear ratios at JLab: BONUS experiment [1] (deuterium), MARATHON experiment [2] ($^3$He and $^3$H targets) and Hall C [3] and CLAS collaboration [4] data. We show that the data at large $x$ can be well described by a combined effect of nuclear momentum distribution, binding and off-shell correction [5,6]. We also discuss the implication of this approach to extract the ratio $F_2$(neutron)$/F_2$(proton) from recent MARATHON measurement [2].
