Query: Hadroproduction of open heavy flavour for PDF analyses   Due to the large masses of the charm and bottom quarks, their production
cross sections are calculable within the perturbative QCD. This makes the
heavy-quark mesons important observables in high-energy collisions of protons
and nuclei. However, the available calculations for heavy-flavored-meson
hadroproduction have been somewhat problematic in reliably describing the cross
sections across the full kinematic range from zero to very high $p_{\rm T}$.
This has put some question marks on the robustness of LHC heavy-flavored-meson
measurements in studying the partonic structure of the colliding hadrons and
nuclei. Here, we introduce SACOT-$m_{\rm T}$ - a novel scheme for open
heavy-flavour hadroproduction within the general-mass variable-flavour-number
formalism that solves this problem. The introduced scheme is an analogue of the
SACOT-$\chi$ scheme often used for deeply-inelastic scattering in global
analyses of PDFs.
