Determination of the strong coupling constant ${\alpha }_s(m_Z)$ from measurements of the total cross section for top-antitop quark production

Thomas Klijnsma, Siegfried Bethke, Günther Dissertori +1

We present a determination of the strong coupling constant ${\alpha }_s(m_Z)$ using inclusive top-quark pair production cross section measurements performed at the LHC and at the Tevatron.…
