Measurement of the Strong Coupling Constant from Inclusive Jet Production at the Tevatron $\bar pp$ Collider

Abstract

We report a measurement of the strong coupling constant, , extracted from inclusive jet production in collisions at 1800 GeV. The QCD prediction for the evolution of with jet transverse energy is tested over the range 40<<450 GeV using for the renormalization scale. The data show good agreement with QCD in the region below 250 GeV. In the text we discuss the data-theory comparison in the region from 250 to 450 GeV. The value of at the mass of the boson averaged over the range 40<<250 GeV is found to be . The associated theoretical uncertainties are mainly due to the choice of renormalization scale () and input parton distribution functions (5%).
