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

PDF Version Also Available for Download.

Description

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.
