Abstract:
Deep inelastic scattering data on $F_2$ structure function obtained
in fixed-target experiments were analyzed in the valence quark
approximation with a next-to-next-to-leading-order accuracy.
The strong coupling constant is found to be
$\alpha_s(M_Z^2) = 0.1157 \pm 0.0022 \text{ (total exp.error)}
$, which is seen to be well compatible
with the average world value.
This study is meant to at least partially explain differences in the predictions
for observables at the LHC
found recently, caused by usage of various sets of parton distribution functions
obtained by different groups.
