Klaus Rabbertz - Determination of the strong coupling constant alpha_s at the LHC
RTG Seminar on Wednesday, January 29th, 2020
An overview is presented of the determinations of the strong coupling constant as performed by the ATLAS and CMS experiments at the LHC. The measurements used for this purpose include jet or event shape based observables as well as Z or W boson and top-antitop pair production. The results will also be discussed in the context of the latest update of the alpha_s world average as reported in the PDG QCD review that was made public in December 2019.
