Description
The strong-coupling constant $\alpha_s(m_Z)$ is measured from the transverse momentum distribution of Z bosons measured at $\sqrt{s} = 1.96$ TeV with the CDF experiment, using predictions based on qt resummation at NNLO+NNLL, as implemented in the DYTURBO program. The measurement is performed through a simultaneous fit of $\alpha_s(m_Z)$, PDFs, and the non-perturbative Sudakov form factor.
