We consider the transverse-momentum distribution of heavy flavours in photon-hadron collisions. We present a formalism in which large transverse-momentum logarithms are resummed to the next-to-leading level, and mass effects are included exactly up to order alpha_em alpha_s^2, so as to retain predictivity at both small and large transverse momenta. Phenomenological applications relevant to charm photoproduction at HERA are given.

Sensitivity of the SHiP experiment to Heavy Neutral Leptons (2018, methodology): “In the simulation we take the angular distribution of Bc mesons to be the same as that of B + mesons, based on comparisons performed with the BCVEGPY [81] and FONLL [82, 83] packages, while we rescale the energy distribution according to the meson mass.”
Expression of interest for the CODEX-b detector (2019, methodology): “In our reach projections, we assume the production cross-section σ(bb̄) ' 500μb and σ(cc̄) is taken to be 20 times larger, based on FONLL estimates [74, 75].”
Measurement of D-meson production at mid-rapidity in pp collisions at √s=7 TeV (2017, methodology): “The fprompt fraction was calculated using the B production cross sections from FONLL calculations [6,41], the B → D + X decay kinematics from the EvtGen package [42] and the efficiencies for feed-down D mesons reported in Fig.”
