$\alpha_s$ from the top quark pair production cross section
Five measurements of the top quark pair production cross section from hadron colliders are compared with the theoretical prediction (up the next-to-next-to-leading order in QCD) in order to determine the strong coupling constant $α_s$ . The determination is performed for several PDF sets. The indivi...

description | Five measurements of the top quark pair production cross section from hadron colliders are compared with the theoretical prediction (up the next-to-next-to-leading order in QCD) in order to determine the strong coupling constant $α_s$ . The determination is performed for several PDF sets. The individual determinations of $α_s$ are combined to form a single best estimate using the Best Linear Unbiased Estimate (BLUE) procedure. Preliminary combined results indicate a higher value of $α_s$ than that determined in a previous extraction of $α_s$ from the top quark pair production cross section. |
