Abstract
The recent CDF single jet inclusive measurements at Fermilab are incor porated in a global next-to-leading order parton analysis of the avail able deep inelastic and related data, Using physically motivated param etric forms of the input parton distributions, we find that it is impo ssible to achieve a simultaneous QCD description of both the CDF jet d istribution for transverse energies E(T) > 200 GeV and the deep inelas tic structure function data for x > 0.3. However, the CDF data for E(T ) < 200 GeV and the deep inelastic data are adequately described provi ded that the QCD coupling alpha(s)(M(Z)(2)) is increased from its pref erred deep inelastic value to alpha(s)(M(Z)(2)) similar or equal to 0. 116-0.120.
