I will examine the uncertainty of perturbative QCD factorization for hadron structure functions in deep inelastic scattering at a large value of the Bjorken variable xB. The focus will be on Target Mass Corrections (TMC) and Jet Mass Corrections (JMC) in the framework of collinear factorization.
The proposed corrections are needed in QCD global fits of parton distribution functions at large-x, low-Q^2 for enlarging the data set and improving the accuracy. This is especially true for polarized targets, where the bulk of the data lies in such a region of phase space. I will discuss some preliminary results including TMC for unpolarized structure functions.
