Evaluation of αS using the ATLAS inclusive jet cross-section data
چکیده انگلیسی
We present a determination of the strong coupling constant using ATLAS inclusive jet cross section data at s=7 TeV, with their full information on the bin-to-bin correlations. Several procedures for combining the statistical information from the data inputs are compared. The theoretical prediction is obtained using NLO QCD with non-perturbative corrections. Our determination uses inputs with transverse momenta between 45 and 600 GeV, the running of the strong coupling being also tested in this range. Good agreement is observed when comparing our result with the world average at the Z-boson scale, as well as with the most recent results from the Tevatron.
