[Bonuslist] Draft Slides for Users' Group Meeting

[Misak Sargsian]

Hi Narbe,
I would like to point your attention to our recent work in Phys. Rev. C
http://journals.aps.org/prc/abstract/10.1103/PhysRevC.93.055205

where Wim Cosyn and I used the BONUS data to apply pole extrapolation
in the extraction of the neutron structure function at large x.

This is in fact the first application of the pole extrapolation procedure to the semi-inclusive
DIS data and only BONUS can allow such an extrapolation.

The extracted structure functions are presented in Fig.5 (see also enclosed figure)  of the mentioned paper which shows
a surprising rise of the neutron to proton structure function ratio at large x.

If this rise will be observed also in the  high Q2 kinematics it will strongly constrain the available theoretical
models of high x structure function of  nucleons.


With Best Regards
Misak
