Abstract
We have used a large set of high-${Q}^{2}$ data on deep-inelastic scattering, dimuon mass distributions, and $\frac{J}{\ensuremath{\psi}}$ ${x}_{F}$ distributions to extract estimates of the ${Q}^{2}$-dependent quark and gluon distribution functions in nucleons. The ${Q}^{2}$ dependence of these functions is parametrized in a manner convenient for predicting a large variety of reactions for ${Q}^{2}\ensuremath{\simeq}4\ensuremath{-}200$ ${(\mathrm{G}\mathrm{e}\mathrm{V}/\mathit{c})}^{2}$ and for extrapolation to the ultrahigh values of ${Q}^{2}$ that will be probed by future accelerators in the TeV energy range.
