The strong-coupling constant is determined from the low-momentum region of the transverse-momentum distribution of Z bosons produced through the Drell–Yan process, using predictions at third order in perturbative QCD. The analysis employs a measurement performed in proton-antiproton collisions at a centre-of-mass energy of 
TeV with the CDF experiment. The determined value of the strong coupling at the reference scale corresponding to the Z-boson mass is
