It enters into all cross-section calculations for processes at the Large Hadron Collider (LHC), whether directly at leading order, or through higher order QCD calculations. It also enters indirectly through the evolution of parton distribution functions (PDFs) and their correlation with the strong coupling. Consequently, as the LHC experiments’ work evolves towards precision physics, accurate knowledge of the strong coupling is becoming increasingly important. The value of the coupling matters also for the question of gauge coupling unification at high scales and for the stability of the universe in any given particle-physics scenario.CERN-TH-2017-268arXiv:1712.05165oai:cds.cern.ch:22974712019
