Hi Narbe,
<div class="">I would like to point your attention to our recent work in Phys. Rev. C</div>
<div class=""><a href="http://journals.aps.org/prc/abstract/10.1103/PhysRevC.93.055205" class="">http://journals.aps.org/prc/abstract/10.1103/PhysRevC.93.055205</a></div>
<div class=""><br class="">
</div>
<div class="">where Wim Cosyn and I used the BONUS data to apply pole extrapolation </div>
<div class="">in the extraction of the neutron structure function at large x.</div>
<div class=""><br class="">
</div>
<div class="">This is in fact the first application of the pole extrapolation procedure to the semi-inclusive </div>
<div class="">DIS data and only BONUS can allow such an extrapolation.</div>
<div class=""><br class="">
</div>
<div class="">The extracted structure functions are presented in Fig.5 (see also enclosed figure) of the mentioned paper which shows </div>
<div class="">a surprising rise of the neutron to proton structure function ratio at large x. </div>
<div class=""><br class="">
</div>
<div class="">If this rise will be observed also in the high Q2 kinematics it will strongly constrain the available theoretical </div>
<div class="">models of high x structure function of nucleons.</div>

<div class="">With Best Regards</div>
