We present a model for inclusive charged lepton‐nucleon and (anti)neutrino‐nucleon cross sections at momentum transfer squared, Q2, ∼1 GeV2. We quantify the impact of existing low‐Q charged‐lepton deep‐inelastic scattering (DIS) data on effects due to high‐twist operators and on the extraction of parton distribution functions (PDFs). No evidence is found for twist‐6 contributions to structure functions (SF), and for a twist‐4 term in the longitudinal SF at x≳0.1. We find that DIS data are consistent with the NNLO QCD approximation with the target mass and phenomenological high twist corrections. For Q2<1 GeV2, we extend extrapolation of the operator product expansion, preserving the low‐Q current‐conservation theorems. The procedure yields a good description of data down to Q2∼0.5 GeV2. An updated set of PDFs with reduced uncertainty and applicable down to small momentum transfers in the lepton‐nucleon scattering is obtained.
