Determination of the strong coupling constant from inclusive jet cross section in ppbar collisions at sqrt(s)=1.96 TeV with the D0 experiment

The strong coupling constant as and its dependence on the momentum scale is determined from the pT dependence of the inclusive jet cross section in p{bar p} collisions at {radical}s = 1.96 TeV measured with the D0 experiment. The jet transverse momentum range of 50 < p{sub T} < 145 GeV contributes to the determination. Using perturbative QCD caclulations to order {theta}({alpha}{sup 3}{sub s}) combined with resummed threshold corrections to order {theta}({alpha}{sup 3}{sub s}) an {alpha}{sub s}(MZ) = 0.1161{sup +0.0041}{sub -0.0048} is obtained. This is the most precise result from a hadron-hadron collider
