New developments in tagged structure functions and PDF determination NLO analysis of expanded set of proton & deuterium data include high-x region (x > 0.5) High-x region requires use of data at lower W & Q 2 CJ15 global PDF analysis target mass corrections, higher twist effects Analysis of high-x data requires careful treatment of subleading 1/Q corrections 2 Correct for nuclear effects in deuteron (binding + off-shell) binding + Fermi motion (well known), nucleon off-shell (less well known) impact on d/u ratio in large-x region Accardi et al., PRD 93, 114017 (2016)
