Neutron structure function and inclusive DIS from 3H and 3He targets at large Bjorken-x

A detailed study of inclusive deep inelastic scattering from mirror A = 3 nuclei at large values of x(Bjorken) is presented. The main purpose is to estimate the theoretical uncertainties on the extraction of F-2(n) from such measurements. Within the convolution approach we confirm the cancellation of nuclear effects at the level of approximate to 1% for x less than or similar to 0.75 in overall agreement with previous findings. However, within models in which modifications of the bound nucleon structure functions are accounted for to describe the EMC effect in nuclei, we find that the nuclear effects may be canceled at a level of approximate to 3% only, leading to an accuracy of approximate to 12% in the extraction of F-2(n)/F-2(p) at x approximate to 0.7 divided by 0.8. Another consequence of bound nucleon modifications is that the iteration procedure does not improve the accuracy of the extraction of F-2(n)/F-2(p).
