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 pT. 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-mT - 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-χ scheme often used for deeply-inelastic scattering in global analyses of PDFs.

Revisiting the D-meson hadroproduction in general-mass variable flavour number scheme
Helenius, Ilkka; Paukkunen, Hannu (Springer, 2018)We introduce a novel realization of the open heavy-flavour hadroproduction in general-mass variable flavour number scheme at next-to-leading order in perturbative QCD. The principal novelty with respect to the earlier works ... -
B-meson hadroproduction in the SACOT-mT scheme
Helenius, Ilkka; Paukkunen, Hannu (Springer, 2023)We apply the SACOT-mT general-mass variable flavour number scheme (GM-VFNS) to the inclusive B-meson production in hadronic collisions at next-to-leading order in perturbative Quantum Chromodynamics. In the GM-VFNS approach ... -
Semileptonic decays of heavy-flavour hadrons
Tolvanen, Alex (2023)Raskaat hadronit, eli hadronit jotka sisältävät vähintään yhden raskaan kvarkin, ovat kiinnostavia, koska niiden massat ovat tarpeeksi suuria jotta niiden tuottovaikutusalat voi laskea jopa pienillä poikittaisliikemäärillä. ... -
Measurements of low-pT electrons from semileptonic heavy-flavour hadron decays at mid-rapidity in pp and Pb-Pb collisions at √sNN = 2.76 TeV
ALICE Collaboration (Springer, 2018)Transverse-momentum (pT) differential yields of electrons from semileptonic heavy-flavour hadron decays have been measured in the most central (0–10%) and in semi-central (20–40%) Pb–Pb collisions at √sNN=2.76 TeV. The ...
