Query: Predictions for $\mathrm{Z}$-boson production in association with a
  $\mathrm{b}$-jet at $\mathcal{O}(\alpha_s^3)$   Precise predictions are provided for the production of a $\mathrm{Z}$-boson
and a $\mathrm{b}$-jet in hadron-hadron collisions within the framework of
perturbative QCD, at $\mathcal{O}(\alpha_s^3)$. To obtain these predictions we
perform the first calculation of a hadronic scattering process involving the
direct production of a flavoured-jet at next-to-next-to-leading order accuracy
in massless QCD, and extend techniques to also account for the impact of finite
heavy-quark mass effects. The predictions are compared to CMS data obtained in
$\mathrm{pp}$ collisions at a centre-of-mass energy of $8~\mathrm{TeV}$, which
are the most precise data from Run I of the LHC for this process, where a good
description of the data is achieved. To allow this comparison we have performed
an unfolding of the data, which overcomes the long-standing issue that the
experimental and theoretical definitions of jet flavour are incompatible.
