Top-quark pole mass extraction at NNLO accuracy

Abstract

We describe our recent NNLO QCD extraction of the top-quark pole mass from fits to experimental data on total inclusive and normalized (multi)-differential cross sections for $t\bar{t}+X$ hadroproduction, using as input various modern PDF + ${\alpha }_s(M_Z)$ sets. We find top-quark mass values compatible among each other and with the PDG 2024 preferred value.
