<i>α</i> _s from DIS data with large <i>x</i> resummations

Abstract The deep inelastic scattering data on the nucleon F 2 structure function, accumulated by Bologna-CERN-Dubna-Munich-Saclay (BCDMS), Stanford Linear Accelerator Center (SLAC) and NMC (New Muon Collaboration) collaborations in fixed-target experiments, were analyzed in the non-singlet approximation within the frameworks of both the conventional <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" overflow="scroll"> <mml:mover accent="true"> <mml:mrow> <mml:mi>M</mml:mi> <mml:mi>S</mml:mi> </mml:mrow> <mml:mrow> <mml:mo stretchy="true">¯</mml:mo> </mml:mrow> </mml:mover> </mml:math> scheme and those with resummations of logarithms at large Bjorken x values. In the latter, such resummations lead to a significant reduction in the factors of Wilson coefficient functions, thereby giving more credibility to the application of perturbation theory in this region.
