abstract = {We extract the top-quark mass value in the on-shell
renormalization scheme from the comparison of theoretical
predictions for $pp \rightarrow t\bar{t} + X$ at
next-to-next-to-leading order (NNLO) QCD accuracy with
experimental data collected by the ATLAS and CMS
collaborations for absolute total, normalized
single-differential and double-differential cross-sections
during Run 1, Run 2 and the ongoing Run 3 at the Large
Hadron Collider (LHC). For the theory computations of
heavy-quark pair-production we use the MATRIX framework,
interfaced to PineAPPL for the generation of grids of theory
predictions, which can be efficiently used a-posteriori
during the fit, performed within xFitter. We take several
state-of-the-art parton distribution functions (PDFs) as
input for the fit and evaluate their associated
uncertainties, as well as the uncertainties arising from
renormalization and factorization scale variation. Fit
uncertainties related to the datasets are also part of the
extracted uncertainty of the top-quark mass and turn out to
be of similar size as the combined scale and PDF
uncertainty. Fit results from different PDF sets agree among
each other within 1$\sigma$ uncertainty, whereas some
datasets related to $t\bar{t}$ decay in different channels
(dileptonic vs. semileptonic) point towards top-quark mass
values in slight tension among each other, although still
compatible within $2.5 \sigma$ accuracy. Our results are
compatible with the PDG 2022 top-quark pole-mass value. Our
work opens the road towards more complex simultaneous NNLO
fits of PDFs, the strong coupling $\alpha_s(M_Z)$ and the
top-quark mass, using the currently most precise
experimental data on $t\bar{t} + X$ total and
multi-differential cross-sections from the LHC.},
