On QCDQ2-evolution of deuteron structure functionF2D(xD,Q2) forxD>1

SummaryThe deep-inelastic deuteron structure function (SF)F2D (xD,Q2) in the covariant approach in light-cone variables is considered. ThexD andQ2-dependences of SF are calculated. The QCD analysis of generated data both for non-cumulativexD<1 and cumulativexD>1 ranges is performed. It is shown that theQ2-evolution of SF is valid for ranges 0.275<xD<0.85 and 1.1<xD<1.4 for the same value of QCD scale parameter Λ. It is found that thexD-dependence of SF for the range is essentially different.
